Description
Technical Field
The invention relates to the field of tobacco processing machinery, in particular to a cabinet changing alarm method and an alarm system for a tobacco shred storage cabinet.
Background
The tobacco shred storage system taking the tobacco shred storage cabinet as a core is an important device for tobacco processing. The conveying direction of the cut tobacco in the cigarette workshop is shown as the direction indicated by an arrow in figure 2, and in the processing process, the cut tobacco 8 produced in the tobacco making process is uniformly distributed on a conveying device 9 in the tobacco storage cabinet 1 through a material distribution vehicle 11, and the cut tobacco is conveyed to a tobacco feeding vibration disc 10 through the conveying device 9. The cigarette making machine 2 sucks the tobacco shreds 8 from the tobacco-feeding vibration disk 10 through the tobacco-feeding air pipe 3 to carry out cigarette making process. The wire storage cabinets 1 connected with the wire feeding vibration discs 10 are provided with a plurality of wire storage cabinets, only one wire storage cabinet is started to supply materials to the rolling and connecting machine 2 each time, the wire storage cabinet is used as a material supply wire storage cabinet, and the other wire storage cabinets stop working. When the residual quantity of the cut tobacco in the feeding and storage cabinet is reduced to be insufficient to supply the cigarette making machine 2, an operator needs to replace the storage cabinet for the cigarette making machine 2 in time, namely, the feeding and storage cabinet with insufficient residual quantity of the cut tobacco is closed, and then the next storage cabinet with sufficient cut tobacco quantity is opened to supply the cigarette making machine 2. But in the actual engineering, the production efficiency is often influenced and even the product quality problem is caused because the cabinet changing time is not easy to grasp. If the cabinet is changed too late, the tobacco shreds 8 in the front and the back batches cannot be connected, so that insufficient feeding in the downstream cigarette process is easily caused, the cut-off of the tobacco shreds 8 of the cigarette making and connecting machine is caused, the production continuity of the subsequent process is influenced, and the production efficiency is reduced. If the cabinet is replaced too early, the current feeding and tobacco storage cabinet is closed under the condition of sufficient tobacco shred amount, so that unnecessary times of replacing the cabinet are increased, and manpower is wasted. Particularly, in engineering practice, one wire storage cabinet is often used for supplying materials for a plurality of winding and connecting machines, and the material using speed difference is large due to the fact that the number of the winding and connecting machines in operation is not fixed, and a fixed cabinet changing period cannot be set.

In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
The invention discloses a cabinet-changing alarm method for a silk storage cabinet, which is used for reminding a rolling and connecting machine 2 to change a silk storage cabinet 1, and comprises the following steps as shown in figure 1:
step S1: acquiring the number of the rolling machines 2 connected with the cut tobacco storage cabinet 1 in operation, the residual percentage of the tailing stage, a correction coefficient, a cut tobacco storage quantity adjustment value, the full-load storage quantity of the feeding cut tobacco storage cabinet 1 and the actual residual percentage of cut tobacco 8 in the feeding cut tobacco storage cabinet 1;
step S2: acquiring preset values according to the number of the cigarette making and tipping machines 2, the residual percentage of the tailing stage, the correction coefficient, the adjustment value of the silk storage amount and the full-load storage amount of the feeding silk storage cabinet 1;
and step S3: judging whether the actual residual percentage is smaller than a preset value or not;
and step S4: if yes, alarming.
Wherein, the full load material storage amount of the feed cut tobacco storage cabinet is the weight of the cut tobacco stored in the feed cut tobacco storage cabinet in the full load state. As shown in figure 2, a plurality of filament storage cabinets 1 connected with the filament feeding vibration plate 10 are provided, only one filament storage cabinet is started to supply the material to the rolling machine 2 at a time, the filament storage cabinet is used as a material supply filament storage cabinet, and the rest filament storage cabinets stop working. The actual remaining percentage is the ratio of the weight of the remaining cut tobacco in the feeding cut tobacco storage cabinet 1 to the full-load storage amount of the feeding cut tobacco storage cabinet. The residual percentage, the correction coefficient and the adjustment value of the wire storage amount in the tailing stage are input into the control system by an operator. The residual percentage in the tailing stage is a theoretical value of the residual percentage of tobacco shreds in the tobacco shred storage cabinet 1 when the discharging process of the tobacco shred storage cabinet 1 enters the tailing stage, the correction coefficient is a coefficient set by an operator according to the actual residual percentage corresponding to an ideal alarm time, and the adjustment value of the tobacco shred storage amount is an adjustment value of the tobacco shred amount set by the operator according to the ideal alarm time.
Specifically, the supply hopper is fully loaded before starting the supply, i.e., the actual remaining percentage of tobacco leaves in the supply hopper before starting the supply is 100%. In the feeding process, the actual residual percentage of the cut tobacco 8 in the cut tobacco storage cabinet 1 is gradually reduced, when the actual residual percentage is reduced to be smaller than a preset value, an alarm is generated to prompt an operator to change the cabinet, namely, the cut tobacco storage cabinet 1 is turned off, and then the next cut tobacco storage cabinet 1 fully loaded with materials is started to feed the cigarette making machine 2. In this embodiment, the size of the preset value is in direct proportion to the number of the cigarette making machines 2, that is, the greater the number of the cigarette making machines 2, the faster the tobacco shred consumption speed is, enough tobacco shreds need to be reserved for the cigarette making machines 2, so as to ensure that the cigarette making machines 2 do not break in the time period from the alarm to the completion of cabinet replacement.
By adopting the technical scheme, the number of the rolling machines 2 connected with the cut tobacco storage cabinet 1 in operation, the full-load material storage amount of the feeding cut tobacco storage cabinet and the actual residual percentage of the cut tobacco 8 in the cut tobacco storage cabinet 1 in the actual operation condition of the cigarette workshop equipment are controlled to alarm to remind an operator to change the cabinet, so that the operator can easily master the cabinet changing time; the situation that the tobacco shreds 8 are cut off due to the fact that an operator operates the cabinet by experience too late is avoided.
Further, as shown in fig. 2, a feeding end 21 of each rolling-up machine 2 is respectively provided with a wire feeding air pipe 3, and the wire feeding air pipe 3 is used for feeding the cut tobacco 8 output by the cut tobacco storage cabinet 1 to the rolling-up machine 2; specifically, a storage bin is arranged on the cigarette making and tipping machine 2, the discharge end of the tobacco feeding air pipe 3 is connected with the storage bin, negative pressure can be provided for the tobacco feeding air pipe 3 after the cigarette making and tipping machine 2 operates, and tobacco shreds 8 are sucked from the tobacco feeding vibration disc 10 through the tobacco feeding air pipe 3 and are fed into the storage bin for the cigarette making and tipping machine 2 to use; a wire feeding vibration disc 10 is arranged between the wire feeding air pipe 3 and the wire storage cabinet 1 and is used for loosening the tobacco 8 output by the wire storage cabinet 1 and transmitting the tobacco 8 to the feeding end of the wire feeding air pipe 3.
The method for acquiring the number of the rolling and connecting machines 2 connected with the silk storage cabinet 1 comprises the following steps:
as shown in fig. 2, a pressure sensor 4 is disposed in each wire feeding air pipe 3, the pressure sensor 4 is configured to detect an actual pressure value in the wire feeding air pipe 3, and when the actual pressure value is greater than a preset pressure value, the pressure sensor 4 generates a pressure signal; specifically, send a discharge end of tuber pipe 3 to be equipped with the fan, send the pressure in the tuber pipe 3 to be the negative pressure, for calculation, the absolute value of negative pressure value in the tuber pipe 3 is got to the actual pressure value, and the preset pressure value is the positive value.
It should be mentioned that before the initial start-up operation of the cigarette making machine 2, the cigarette making machine 2 does not provide negative pressure to the wire feeding air pipe 3, the pressure in the wire feeding air pipe 3 is zero (smaller than a preset value), and the pressure sensor 4 does not generate a pressure signal. Therefore, whether the cigarette making and tipping machine 2 is in operation can be judged according to the pressure signal.
Receiving the pressure signal and judging whether the pressure signal is an effective pressure signal or not;
the number of received effective pressure signals is calculated as the number of active cigarette winders 2. In the embodiment, the wire feeding air pipe 3 starts wire feeding work after the cigarette making machine 2 operates, whether the cigarette making machine 2 operates can be indirectly judged by detecting the pressure value in the wire feeding air pipe 3, the quantity of the cigarette making machines 2 connected with the cigarette storage cabinet 1 in operation can be counted in a cigarette workshop adopting the method without performing complex changes on equipment, and the method is simple and easy to operate.
Further, determining whether the pressure signal is a valid pressure signal comprises:
judging whether the received pressure signal is interrupted;
if the pressure signal does not exist, the cigarette making and tipping machine 2 is in operation, the pressure signal is an effective pressure signal;
if yes, judging whether the interruption time of the pressure signal exceeds the preset time or not;
if not, the pressure signal is a valid pressure signal.
Specifically, after the storage bin of the cigarette making and tipping machine 2 is full of the cut tobacco 8, the cigarette making and tipping machine 2 stops providing negative pressure for the cut tobacco feeding air pipe 3, the cut tobacco feeding air pipe 3 interrupts the cut tobacco feeding and continues to start the cut tobacco feeding after the cut tobacco 8 in the storage bin is partially consumed, and at the moment, the pressure signal is interrupted; in some extreme cases, the wire feeding air pipe 3 starts to continue feeding after the tobacco shreds 8 in the storage bin are consumed, the time for the tobacco shreds 8 in the full storage bin to be consumed is the preset time, and if the interruption time does not exceed the preset time, the pressure signal is considered as an effective pressure signal, namely, the cigarette making machine 2 is in continuous operation.
Further, the preset pressure value is 20-300Pa, namely the tobacco shreds 8 can be conveyed only when the pressure in the tobacco shred feeding air pipe 3 reaches 20-300Pa, and the pressure sensor 4 generates a pressure signal for judging whether the cigarette making and tipping machine 2 is in operation. In the present example, the preset pressure value is 80Pa; the preset pressure value is also related to the model of the cigarette making machine 2, the diameter and length of the air feed pipe 3, the type and shape of the tobacco shred 8, and the like, so in other embodiments, the preset pressure value can be set to 20Pa, 30Pa, 100Pa, 150Pa, 200Pa, 300Pa, and the like, and the preset time is 5 minutes, that is, the time for the tobacco shred 8 in the full storage bin to be consumed up is 5 minutes.
Further, the preset value is calculated by the following formula:
wherein Y is a preset value; a is the residual percentage of the tailing stage; b is a correction coefficient; c is the full load stock amount of the supply silk storage cabinet; d is a stored yarn amount adjusting value; and E is the number of the rolling machines connected with the silk storage cabinet in operation.
Specifically, a is the remaining percentage of shredded tobacco 8 in the shredded tobacco storage cabinet 1 when the feeding process of the shredded tobacco storage cabinet 1 enters the tailing stage, and an operator needs to prepare to change the cabinet at least before the shredded tobacco storage cabinet 1 enters the tailing stage. The residual percentage A in the tailing stage is set by an operator according to the models, conveying speeds and tobacco types of different tobacco shred storage cabinets 1, and in the embodiment, the value of A is 9%. In other embodiments, the a value may also be 5%, 12%, or 15%. The operation of cigarette workshops verifies that the corresponding A value range of each existing cut tobacco storage cabinet 1 is 5% -15%. C is the full load storage quantity (unit: kg) of the feeding and storing tobacco shred cabinet, namely the weight of the tobacco shreds stored in the feeding and storing tobacco shred cabinet in the full load state. In the embodiment, the full-load material storage amount of each wire storage cabinet 1 is basically the same, the weight error is controllable, and the influence on the calculation result of the calculation formula is negligible. Therefore, different filament storage cabinets can adopt the same C value in the calculation formula. B is a correction coefficient, D is a filament storage amount adjustment value, and the B value and the D value are obtained by calculation of an operator according to a plurality of groups of data including E, C and A and a preset value Y of an ideal cabinet changing time corresponding to each group of numerical values. In other embodiments, the numerical value of the adjustment value D of the stored tobacco shred amount may also be determined by an operator according to actual conditions, and specifically, a median value of a range of the full-load stored material amount of the stored tobacco shred cabinet 1 may be adopted, and if the types of the tobacco shreds 8 in the stored tobacco shred cabinet 1 in different batches of production are different and the production process is different, the range of the full-load stored material amount of the stored tobacco shred cabinet 1 is 4000kg-6000kg, and the median value of the adjustment value D of the stored tobacco shred amount is 4000kg-6000kg, that is, 5000kg.
Further, obtaining the actual remaining percentage of shredded tobacco 8 in the feeding shredded tobacco storage cabinet 1 includes:
acquiring the actual running stroke of the cut tobacco 8 in the feeding and cut tobacco storage cabinet 1 (namely the running stroke of the discharged part of the cut tobacco 8);
calculating the stroke difference value between the total stroke (i.e. the stroke of all the cut tobaccos 8 required to be discharged) and the actual stroke of the cut tobaccos 8 required to be operated in the feeding cut tobacco storage cabinet 1;
and calculating the ratio of the stroke difference value to the total stroke, namely the actual residual percentage.
As shown in fig. 4, the tobacco shred 8 in the tobacco shred storage cabinet 1 is homogeneous tobacco shred and the thickness of the cloth is uniform, so that the residual percentage of the weight of the tobacco shred 8 in the tobacco shred storage cabinet 1 can be calculated through an actual stroke and a total stroke.
Further, obtaining the actual remaining percentage of shredded tobacco 8 in the feeding shredded tobacco storage cabinet 1 includes:
detecting metal blocks 6 on a detection disc 61 arranged on a transmission shaft 93 of a conveying device 9 through a photoelectric sensor 5, sending a pulse to a first processing unit after the photoelectric sensor 5 detects each metal block 6, receiving the pulse output by the photoelectric sensor 5 by the first processing unit, and calculating the number of received pulses as an actual pulse value;
the first processing unit calculates a pulse difference value between a preset pulse value and an actual pulse value, wherein the preset pulse value is a total pulse value measured by the photoelectric sensor 5 after all the cut tobacco 8 is output;
the first processing unit calculates the ratio of the pulse difference value to a preset pulse value, namely the actual residual percentage.
In the above-described embodiment, the number of rotations of the transmission shaft 93 can be calculated from the actual pulse value, and the number of rotations of the pulley 91 and the stroke of the belt 92 can be calculated. By adopting the technical scheme, the actual residual percentage of the cut tobacco 8 in the cut tobacco storage cabinet 1 is obtained by detecting the pulse number, the accuracy of the detected actual residual percentage can be improved, the detection process can be simplified, the equipment structure can be simplified, and the installation space and the cost can be saved.
Specifically, as shown in fig. 3, the metal blocks 6 are uniformly distributed on the detection disk 61 around the axis of the detection disk 61, and the number of the metal blocks 6 is 12.
Further, the alarm mode includes: whistling and/or flashing lights and/or displaying alarm information.
The invention also discloses a cabinet-changing alarm system of the silk storage cabinet, which is used for reminding a rolling and connecting machine 2 to change the silk storage cabinet 1, and comprises the following components as shown in figures 3 and 4:
a first detection device 51 for acquiring the actual remaining percentage of shredded tobacco 8 in the feeding and shredded tobacco storage cabinet 1;
