[0028] Example 1

[0029] Figure 1This is a flowchart of a control method in an embodiment of the present invention. This embodiment is applicable to the coordinated control of the horizontal and vertical trolleys of the leaf storage cabinet in the tobacco processing workshop of a cigarette manufacturing enterprise. The method can be executed by the control device in this embodiment of the present invention, which can be implemented in software and / or hardware, such as... Figure 1 As shown, the method specifically includes the following steps:

[0030] S101. Obtain the stacking length, input amount, and flow time of the material in the storage tank, and obtain the horizontal trolley coefficient and the vertical trolley coefficient.

[0031] The embodiments of the present invention are applicable to the parameter settings of the leaf storage cabinet in the tobacco processing workshop of cigarette manufacturing enterprises, so as to achieve the coordinated control of the horizontal and vertical trolleys of the leaf storage cabinet, on the premise of meeting the uniformity of tobacco leaf mixing.

[0032] It is known that a tobacco storage cabinet is a large cabinet in a tobacco factory used to temporarily store loose tobacco leaves. In this embodiment, the material can be reconstituted tobacco leaves. Reconstituted tobacco leaves and tobacco sheets have significant differences in appearance. Compared with tobacco sheets, reconstituted tobacco leaves are more regular in shape, have no veins, and have a uniform color. They can be visually distinguished from tobacco sheets.

[0033] The stacking length of the material in the leaf storage cabinet can be the length of the material stacking from one end to the other, and the unit can be cm.

[0034] In actual operation, the input of reconstituted tobacco leaves can be divided into two types: one is to input all the tobacco leaves at once without any gaps between them, and the other is to input all the tobacco leaves in several batches without any gaps between them. In this embodiment, the input amount can be based on the amount of reconstituted tobacco leaves input in a single concentrated batch.

[0035] In this embodiment, the reconstituted tobacco flow time can be divided into full-input flow time and peak-input flow time according to the calculation method. Taking the exit of the secondary feeding process as the observation point, the full-input flow time is the time span from the appearance of reconstituted tobacco to its complete disappearance within a continuous period, and the peak-input flow time is the time span from the increase of reconstituted tobacco to more than 10% to the decrease of reconstituted tobacco to less than 10% within a continuous period. In the specific implementation process, the flow time can be calculated separately for the full-input flow time and the peak-input flow time. The belt speed of the straight trolley, the belt speed of the transverse trolley, and the trolley speed of the straight trolley should be between the results of the two flow time calculations and should not exceed them.

[0036] It should be noted that the traverse trolley can be a fabric trolley with a conveyor belt whose direction of movement is parallel to the long side of the leaf storage tank. The movement speed of the traverse trolley can include two parameters: the trolley's running speed and the belt's running speed.

[0037] Among them, the lateral trolley coefficient can be a representation of the physical dimensions of the lateral trolley, and is set by actual measurement and to prevent material blockage and breakage.

[0038] It should be noted that the trolley can be a fabric trolley with a conveyor belt whose direction of movement is perpendicular to the long side of the leaf storage tank. The speed of the trolley can include both the trolley's running speed and the belt's running speed.

[0039] Among them, the straight trolley coefficient can be a representation of the physical dimensions of the straight trolley, and is set by actual measurement and to prevent material blockage and breakage.

[0040] S102. Determine the target velocity set based on the stacking length, input quantity, flow time, lateral trolley coefficient, and straight trolley coefficient.

[0041] It should be noted that the target speed set can be a set composed of the trolley speed and belt speed of the lateral trolley and the trolley speed and belt speed of the longitudinal trolley.

[0042] Specifically, based on the input amount of reconstituted tobacco leaves, the flow time, and the requirements for uniformity and smoothness of tobacco leaf blending, the trolley speed and belt speed of the transverse trolley and the trolley speed and belt speed of the straight trolley are calculated. Among them, the uniformity of tobacco leaf blending refers to the uniform mixing of all tobacco leaves (reconstituted tobacco leaves and tobacco flakes) according to the leaf group formula ratio, so that at any moment when the material leaves the container, the proportion of each leaf group component is close to the leaf group formula.

[0043] In actual operation, the material on the straight-running trolley is laid in a straight line, while the trolley on the transverse-running trolley moves a certain distance at regular intervals, and speed is not considered a factor.

[0044] S103. Determine the motor frequency set based on the target speed set, and control the transverse and straight trolleys based on the motor frequency set.

[0045] In this embodiment, the movement speed of the lateral and longitudinal trolleys is determined by the frequency of the drive motors. The higher the motor frequency, the faster the belt speed and the trolley's running speed. The set of motor frequencies can be the set of motor frequencies that determine the trolley's running speed, belt speed, and the trolley's running speed and belt speed of the longitudinal trolley.

[0046] Specifically, based on the correlation between each speed in the target speed set and the drive motor frequency, a set of motor frequencies is determined. The speeds of the lateral and longitudinal trolleys are then set based on the motor frequencies within this set, thus achieving control of the lateral and longitudinal trolleys. The correlation between each speed and each motor frequency is based on measured values ​​or theoretical calculations; speeds can be accurate to 1 cm / s, and motor frequencies to 0.5 Hz.

[0047] This invention, through obtaining the stacking length, input quantity, and flow time of materials within the leaf storage tank, and acquiring the horizontal and vertical trolley coefficients, determines a target speed set based on these parameters. A motor frequency set is then determined based on this target speed set, allowing for control of the horizontal and vertical trolleys. By calculating different motor frequency parameters based on the input quantity, flow time, horizontal trolley coefficient, and vertical trolley coefficient, the invention enables coordinated control of the horizontal and vertical trolleys within the leaf storage tank. This coordinated control of the horizontal and vertical trolleys ensures the uniformity of batch material blending.

[0048] Optionally, a target velocity set can be determined based on the stack length, input quantity, flow time, lateral trolley coefficient, and straight trolley coefficient, including:

[0049] The speed of the trolley for the straight-running vehicle is determined based on the stack length and flow time.

[0050] Specifically, the speed of the trolley in the straight-line carriage is calculated based on the stacking length L of the material in the storage cabinet from one end to the other and the visually estimated flow time T of the reconstituted tobacco leaves on the conveyor belt in front of the traverse carriage. .

[0051] The speed of material flow on the trolley is determined based on the input amount, flow time, and trolley coefficient.

[0052] Specifically, the speed of tobacco leaf flow on the straight trolley is determined based on the single input amount M of the material, the visually estimated flow time T of the reconstituted tobacco leaves on the conveyor belt before the traverse trolley, and the coefficient A of the straight trolley. .

[0053] The speed of material flow on the trolley is determined based on the input amount, flow time, and trolley coefficient.

[0054] Specifically, the flow rate of tobacco leaves on the trolley is determined based on the single input quantity M of the material, the visually estimated flow time T of the reconstituted tobacco leaves on the conveyor belt in front of the trolley, and the coefficient B of the trolley. .

[0055] The target speed set is composed of the speed of the trolley running in the straight direction, the speed of the material flow on the straight trolley, and the speed of the material flow on the trolley in the transverse direction.

[0056] In practice, using the peak input flow time as the lower limit parameter of the collaborative control model and the total input flow time as the upper limit parameter, the following collaborative control model can be constructed:

[0057] ;

[0058] Where M represents the amount of reconstituted tobacco leaves added at one time, in kg. T represents the reconstituted tobacco leaf flow time, in s. This indicates the mass per unit volume of tobacco leaves on a straight-running trolley, expressed in kg / cm³. 3 . This indicates the width of the tobacco pile on the straight-running vehicle, in cm. This indicates the height of the tobacco leaves piled up on the straight-running vehicle, in cm. This indicates the speed at which the tobacco leaves flow on the trolley, measured in cm / s. This indicates the mass per unit volume of tobacco leaves on the rolling stock, expressed in kg / cm². 3 . This indicates the width of the tobacco pile on the cross-country vehicle, in cm. This indicates the height of the tobacco pile on the rolling stock, in cm. This indicates the speed at which the tobacco leaves flow on the rolling trolley, measured in cm / s.

[0059] Specifically, based on the above collaborative control model, the speed of the straight-running trolley, the speed of the material flow on the straight-running trolley, and the speed of the material flow on the transverse trolley can be obtained from the known parameters in the formula.

[0060] Optionally, the trolley speed of the straight-runner can be determined based on the stack length and flow time, including:

[0061] Number of times to obtain cloth.

[0062] In this embodiment, the number of times n is applied is set according to the actual situation, representing the number of times the reconstituted tobacco leaves are applied in a single pass along the longitudinal direction of the storage cabinet.

[0063] The speed of the trolley is determined based on the stack length, flow time, and number of fabric passes.

[0064] In the specific implementation process, the relationship between the stacking length, flow time, number of fabric application cycles, and the running speed of the straight-running trolley can be expressed as follows:

[0065] T;

[0066] Where n represents the number of times the material is laid, taking the natural number 1, 2, 3, ..., without a unit. L represents the length of the material stack in the leaf storage tank from one end to the other, i.e., the stack length, in cm. The speed of the trolley in a straight line is expressed in m / s = 10 cm / s. T represents the time it takes for the reconstituted tobacco leaves to flow, expressed in seconds.

[0067] Specifically, the calculation method for determining the trolley speed of the straight-line trolley based on the stacking length, flow time, and number of fabric placements can be expressed as follows: .

[0068] Optionally, a set of motor frequencies is determined based on a target speed set, and the transverse and longitudinal trolleys are controlled based on this set of motor frequencies, including:

[0069] The system queries a preset relationship table based on the speed of the trolley to obtain the corresponding frequency value of the trolley's motor. Then, it sets the trolley's motor based on the motor frequency value to achieve control of the trolley.

[0070] In this embodiment, the frequency of the trolley belt motor, the frequency of the trolley carriage motor, and the frequency of the transverse trolley belt motor are adjusted, and the speeds of the trolley belt, the trolley carriage, and the transverse trolley belt at different frequencies are measured to establish a preset relationship table between the frequency of each motor and the speed of the belt or carriage.

[0071] Specifically, according to the standard table of belt speed of the straight trolley, belt speed of the transverse trolley, trolley running speed of the straight trolley and frequency of each motor, the optimal frequency of the trolley running motor of the straight trolley is found, and the frequency of the trolley running motor of the straight trolley is set accordingly.

[0072] The speed of material flow on the trolley is used to query a preset relationship table to obtain the frequency value of the trolley belt motor. The trolley belt motor is then set based on the frequency value to achieve control of the trolley belt.

[0073] Specifically, by referring to the standard table of belt speeds for the straight trolley, belt speeds for the transverse trolley, trolley travel speeds for the straight trolley, and frequencies of each motor, the optimal frequency of the straight trolley belt motor is obtained, and the frequency of the straight trolley belt motor is set accordingly.

[0074] The speed of material flow on the trolley is used to query a preset relationship table to obtain the frequency value of the trolley belt motor. The trolley belt motor is then set based on the frequency value to achieve control of the trolley.

[0075] Specifically, according to the standard table of belt speed of the straight trolley, belt speed of the transverse trolley, trolley running speed of the straight trolley and frequency of each motor, the optimal frequency of the transverse trolley belt motor is found, and the frequency of the transverse trolley belt motor is set accordingly.

[0076] Optionally, obtain the horizontal running car coefficient and the vertical running car coefficient, including:

[0077] Obtain the horizontal distance between the edge strips on both sides of the trolley, and determine the stacking width of the material on the trolley based on the horizontal distance between the edge strips on both sides of the trolley.

[0078] Specifically, the width of material stacking on the scooter. The horizontal distance between the pressure strips on both sides of the trolley is used as the upper limit to ensure that the material does not fall on the pressure strips of the belt, thus ensuring the uniformity of material mixing.

[0079] Obtain the lateral width of the trolley's discharge port, and determine the material accumulation height on the trolley based on the lateral width of the trolley's discharge port.

[0080] Specifically, the stacking height of materials on the trolley. The horizontal width of the material drop opening of the trolley should be the upper limit, not exceeding two-thirds, to avoid the material being too high and causing blockage of the drop opening.

[0081] Obtain the longitudinal width of the horizontal trolley's discharge port, and determine the material accumulation width on the vertical trolley based on the longitudinal width of the horizontal trolley's discharge port.

[0082] Specifically, the width of the tobacco leaf accumulation on the straight-running vehicle. The longitudinal width of the material drop opening of the trolley should be the upper limit, not exceeding two-thirds, to avoid the material being too wide and causing blockage of the drop opening.

[0083] Obtain the height from the outlet of the horizontal trolley to the belt of the vertical trolley, and determine the material accumulation height on the vertical trolley based on the height from the outlet of the horizontal trolley to the belt of the vertical trolley.

[0084] Specifically, the height of tobacco leaves piled up on the straight-running vehicle. The height from the outlet of the horizontal trolley to the belt of the vertical trolley should not exceed two-thirds to avoid material blockage at the outlet due to excessive material height.

[0085] Obtain the density of the material, and determine the trolley coefficient based on the density, the stacking width of the material on the trolley, and the stacking height of the material on the trolley.

[0086] It should be noted that the density of a material can be the mass per unit volume, and the unit can be kg / cm³. 3。

[0087] In actual operation, the mass per unit volume of tobacco leaves on the trolley Mass per unit volume of tobacco leaf on a straight-running vehicle The default value should remain consistent, uniformly representing the material's density ρ. Different grades or specifications of material may have different densities; actual measurements should prevail. Simultaneously, ensure that the tobacco sheets are not compressed to avoid affecting their expansion and causing clumping.

[0088] Specifically, the calculation method for the cross-track coefficient B can be expressed as follows: .

[0089] The straight-running trolley coefficient is determined based on density, the width of material accumulation on the straight-running trolley, and the height of material accumulation on the straight-running trolley.

[0090] Specifically, the calculation method for the straight-line vehicle coefficient A can be expressed as follows: .

[0091] Optionally, the density of the material can be obtained, including:

[0092] Obtain the mass, height, top width, and bottom width of the material at the target length on the trolley, and determine the cross-sectional area of ​​the material based on the mass, height, top width, and bottom width.

[0093] The target length can be the length of the material cut off on the trolley. This length can be set by the user according to the actual situation, and this embodiment does not limit it.

[0094] Specifically, a certain length of tobacco shreds is cut from the trolley and weighed, and the height of the material level, the width of the top of the material, and the width of the bottom of the material are measured. Based on this, the cross-sectional area of ​​the material is calculated.

[0095] The density of the material is determined based on the target length, mass, and cross-sectional area of ​​the material.

[0096] Specifically, the density ρ of the material on the conveyor belt is calculated using the material's cross-sectional area, target length, and mass. = =ρ, and finally the coefficient B of the horizontal running car and the coefficient A of the vertical running car of this grade (specification) are calculated.

[0097] As an exemplary description of an embodiment of the present invention, the following example illustrates the coordinated control method of the horizontal and vertical trolleys in a leaf storage tank, the process of which is as follows:

[0098] (1) The reconstituted tobacco leaves of brand X are fed in batches with the tobacco leaves spaced apart between the thin sheets. Each batch of reconstituted tobacco leaves is fed in one box (specification 180kg / box), that is, the amount of reconstituted tobacco leaves fed in one batch is M=180kg.

[0099] (2) The horizontal distance between the edge strips on both sides of the cross carriage is 30cm, with a one-fifth margin reserved on each side, to obtain the parameters. =18cm.

[0100] (3) The transverse width of the material drop opening of the trolley is 42cm. Taking two-thirds of this width, we obtain the parameters. =28cm.

[0101] (4) The longitudinal width of the material drop opening of the trolley is 30cm. Take two-thirds of this width to obtain the parameters. =20cm.

[0102] (5) The height from the outlet of the horizontal trolley to the belt of the vertical trolley is 24cm. Take two-thirds of this height to obtain the parameters. =16cm.

[0103] (6) During normal production, take a 10cm length of material from the trolley and mark it. The material has a height of 10cm in the middle, a top width of 17cm, and a bottom width of 23cm. Collect the material and weigh it to 5kg. The parameter ρ = 0.0025kg / cm3 is obtained.

[0104] (7) Calculate the coefficient B of the horizontal running car = 1.26 kg / cm and the coefficient A of the straight running car = 0.8 kg / cm.

[0105] (8) Measure the distance L = 205cm between the material in the leaf storage cabinet from one end to the other.

[0106] (9) During normal production, the flow time of reconstituted tobacco leaves is visually measured on the conveyor belt in front of the trolley, and the flow time of the total input is T1=240s and the flow time of the peak input is T2=300s.

[0107] (10) According to the formula , , Calculations were made based on peak input flow time and two fabric placement operations, yielding the following results: =0.4cm / s, =0.6cm / s, =1.4cm / s.

[0108] (11) When the machine is running idle, adjust the frequency of the drive motors of the straight trolley belt, the horizontal trolley belt and the straight trolley car respectively, and measure the running speed of the straight trolley belt, the horizontal trolley belt and the straight trolley car simultaneously. Combine the best speeds obtained from the above measurements, the frequency of the drive motors of the straight trolley belt, the horizontal trolley belt and the straight trolley car are 42Hz, 48Hz and 50Hz respectively.

[0109] The technical solution of this invention, based on the significant differences in appearance between reconstituted tobacco leaves and tobacco flakes, takes reconstituted tobacco leaves as the target material. By considering the input amount of reconstituted tobacco leaves, flow time, relevant dimensional information of the straight and horizontal trolleys and the leaf storage cabinet, as well as uniformity requirements, a collaborative control model for the horizontal and straight trolleys of the leaf storage cabinet is established. Based on this model, the setting of various parameters of the leaf storage cabinet is guided, and different motor frequency parameters are set to ensure uniform blending and stable flow of tobacco flakes and reconstituted tobacco leaves, thus ensuring the uniformity of batch material blending.
