For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.
The invention discloses a cabinet changing alarm method for a wire storage cabinet, which is used for reminding a wire storage cabinet 1 to be changed for a crimping machine 2, and comprises the following steps as shown in figure 1:
step S1: acquiring the number of the rolling machines 2, the residual percentage of the tailing stage, the correction coefficient, the wire storage quantity adjustment value, the full-load stock quantity of the feeding wire storage cabinet 1 and the actual residual percentage of the cut tobacco 8 in the feeding wire storage cabinet 1 which are connected with the wire storage cabinet 1 in operation;
Step S2: acquiring preset values according to the number of the crimping machines 2, the residual percentage of the tailing stage, the correction coefficient, the wire storage quantity adjustment value and the full-load stock quantity of the feeding wire storage cabinet 1;
Step S3: judging whether the actual residual percentage is smaller than a preset value;
Step S4: if yes, alarming is carried out.
Wherein, the full-load stock quantity of the feeding and yarn storage cabinet is the weight of the cut tobacco stored in the feeding and yarn storage cabinet under the full-load state. As shown in fig. 2, there are a plurality of wire storage cabinets 1 connected with the wire feeding vibration disc 10, only one wire storage cabinet is started to feed the winding machine 2 at a time, the wire storage cabinet is a feeding wire storage cabinet, and the rest wire storage cabinets stop working. The actual remaining percentage is the ratio of the weight of the remaining tobacco shreds in the feeding and storing cabinet 1 to the full-load stock quantity of the feeding and storing cabinet. The residual percentage, correction coefficient and wire storage quantity adjustment value of 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 the tobacco shreds in the tobacco storage cabinet 1 when the discharging process of the tobacco 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 the ideal alarm time, and the tobacco storage quantity adjustment value is a tobacco quantity adjustment value set by the operator according to the ideal alarm time.
Specifically, the feeding wire storage cabinet is in a full-load state before starting feeding, namely, the actual residual percentage of tobacco leaves in the feeding wire storage cabinet is 100 percent before starting feeding. In the feeding process, the actual residual percentage of the tobacco shreds 8 in the tobacco storage cabinet 1 is gradually reduced, and 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 tobacco storage cabinet 1 is turned off, and then the next tobacco storage cabinet 1 filled with materials is started to feed the cigarette making machine 2. In this embodiment, the preset value is proportional to the number of the cigarette making machines 2, that is, the greater the number of the cigarette making machines 2, the faster the speed of consuming the cut tobacco 8, and enough cut tobacco needs to be reserved for the cigarette making machines 2, so as to ensure that the cigarette making machines 2 will not break in the time period from the alarm to the cabinet replacement completion.
By adopting the technical scheme, the control alarm reminds an operator of changing the cabinet based on the number of the rolling machines 2 connected with the tobacco storage cabinet 1 in operation, the full-load stock quantity of the feeding tobacco storage cabinet and the actual residual percentage of the tobacco shreds 8 in the tobacco storage cabinet 1 in the actual condition of the operation of the cigarette workshop equipment, so that the operator can easily grasp the cabinet changing time; avoiding the cut-off of the tobacco shreds 8 caused by too late cabinet replacement by operators through experience operation.
Further, as shown in fig. 2, the feeding end 21 of each cigarette making machine 2 is respectively provided with a wire feeding air pipe 3, and the wire feeding air pipes 3 are used for feeding the cut tobacco 8 output by the wire storage cabinet 1 to the cigarette making machine 2; specifically, a storage bin is arranged on the cigarette making and connecting machine 2, the discharge end of the wire feeding air pipe 3 is connected with the storage bin, the cigarette making and connecting machine 2 can provide negative pressure for the wire feeding air pipe 3 after running, and cut tobacco 8 is sucked from the wire feeding vibration disc 10 through the wire feeding air pipe 3 and fed into the storage bin for the material of the cigarette making and connecting machine 2; 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 cut tobacco 8 output by the wire storage cabinet 1 and conveying the cut tobacco 8 to the feeding end of the wire feeding air pipe 3.
The acquisition of the number of the running crimping machines 2 connected to the wire storage cabinet 1 comprises:
As shown in fig. 2, a pressure sensor 4 is arranged in each wire feeding air pipe 3, the pressure sensor 4 is used for detecting the actual pressure value in the wire feeding air pipe 3, and when the actual pressure value is greater than the preset pressure value, the pressure sensor 4 generates a pressure signal; specifically, a fan is arranged at the discharge end of the wire feeding air pipe 3, the pressure in the wire feeding air pipe 3 is negative pressure, and for the convenience of calculation, the absolute value of the negative pressure value in the wire feeding air pipe 3 is taken as the actual pressure value, and the preset pressure value is a positive value.
It should be noted that, before the crimping machine 2 is started for the first time, the crimping machine 2 does not provide negative pressure for the wire feeding air pipe 3, the pressure in the wire feeding air pipe 3 is zero (less than a preset value), and the pressure sensor 4 does not generate a pressure signal. Therefore, whether the crimping machine 2 is in operation can be judged according to the presence or absence of 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 the splicer 2 in operation. In this embodiment, the wire feeding air pipe 3 starts the wire feeding operation after the wire winding machine 2 operates, and whether the wire winding machine 2 operates can be indirectly judged by detecting the pressure value in the wire feeding air pipe 3, so that the number of the wire winding machines 2 in operation connected with the wire storage cabinet 1 can be counted without complex changes to equipment in a cigarette workshop adopting the method, and the method is simple and easy to operate.
Further, determining whether the pressure signal is a valid pressure signal includes:
Judging whether the received pressure signal has a break or not;
If the pressure signal does not exist, indicating that the crimping machine 2 is in operation, the pressure signal is an effective pressure signal;
if yes, judging whether the break time of the pressure signal exceeds the preset time;
if not, the pressure signal is an effective pressure signal.
Specifically, when the tobacco shreds 8 in the storage bin of the cigarette making and connecting machine 2 are fully stored, the cigarette making and connecting machine 2 stops providing negative pressure for the tobacco shred feeding air pipe 3, the tobacco shred feeding air pipe 3 can interrupt the tobacco shred feeding and continue to start the tobacco shred feeding after the tobacco shreds 8 in the storage bin are partially consumed, and at the moment, the pressure signal can be interrupted; in some extreme cases, the wire feeding air pipe 3 starts to continue wire feeding after the cut tobacco 8 in the storage bin is consumed, the time spent for the cut tobacco 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 to be an effective pressure signal, namely, the lap joint machine 2 is in continuous operation.
Further, the preset pressure value is 20-300Pa, that is, the cut tobacco 8 can be conveyed only when the pressure in the cut tobacco feeding air pipe 3 reaches 20-300Pa, and the pressure sensor 4 generates a pressure signal at the moment so as to judge whether the crimping machine 2 is in operation. In this 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 wire feeding pipe 3, the type and shape of the cut tobacco 8, and the like, so in other embodiments, the preset pressure value may be set to 20Pa, 30Pa, 100Pa, 150Pa, 200Pa, 300Pa, and the like, and the preset time is 5 minutes, that is, the time taken for the cut tobacco 8 to be consumed in the full storage bin is 5 minutes.
Further, the calculation formula of the preset value is:
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 quantity of the feeding yarn storage cabinet; d is a yarn storage amount adjustment value; e is the number of running crimping machines connected to the wire storage cabinet.
Specifically, a is the remaining percentage of tobacco shreds 8 in the storage cabinet 1 when the feeding process of the storage cabinet 1 enters the tailing stage, and an operator needs to prepare for cabinet replacement at least before the storage cabinet 1 enters the tailing stage. The remaining percentage A in the tailing stage is set by an operator according to the model number, the conveying speed and the tobacco types of different tobacco 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 a cigarette workshop proves that the range of the corresponding A value of each existing cut tobacco storage cabinet 1 is 5% -15%. C is the full-load stock quantity (unit: kg) of the feeding and yarn storage cabinet, namely the weight of the cut tobacco stored in the feeding and yarn storage cabinet under the full-load state. In this embodiment, the full-load stock quantity 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, the same C value can be adopted for different wire storage cabinets in the calculation formula. B is a correction coefficient, D is a wire storage quantity adjustment value, and B and D are calculated by an operator according to a preset value Y of the ideal cabinet changing time corresponding to a plurality of groups of data containing E, C and A and each group of values. In other embodiments, the value of the storage amount adjustment value D may be determined by an operator according to actual situations, and specifically, a median value of a full-load storage amount range of the storage tank 1 may be adopted, for example, the storage tank 1 has different types of the cut tobaccos 8 in different batches of production and different production processes, and if the corresponding full-load storage amount range of the storage tank 1 is 4000kg-6000kg, the value of the storage amount adjustment value D is a median value of a 4000kg-6000kg range, that is, 5000kg.
Further, the obtaining of the actual remaining percentage of the cut tobacco 8 in the feeding and storing cabinet 1 comprises:
acquiring the actual travel of the cut tobacco 8 in the feeding and storage cabinet 1 (namely, the travel of the discharged part of the cut tobacco 8);
calculating the difference between the total travel of the cut tobacco 8 required to run in the feeding and storage cabinet 1 (namely, the travel of all cut tobacco 8 required to run in discharging) and the actual travel;
And calculating the ratio of the travel difference value to the total travel, namely the actual remaining percentage.
As shown in fig. 4, the cut tobacco 8 in the tobacco storage 1 is a homogeneous cut tobacco and has a uniform cloth thickness, and therefore, the remaining percentage by weight of the cut tobacco 8 in the tobacco storage 1 can be calculated by the actual stroke and the total stroke.
Further, the obtaining of the actual remaining percentage of the cut tobacco 8 in the feeding and storing cabinet 1 comprises:
The photoelectric sensor 5 detects the metal blocks 6 on the detection disc 61 arranged on the transmission shaft 93 of the conveying device 9, and after each time the photoelectric sensor 5 detects one metal block 6, the photoelectric sensor 5 sends a pulse to the first processing unit, and the first processing unit receives the pulse output by the photoelectric sensor 5 and calculates the number of times of the received pulse 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 tobacco shreds 8 are output;
The first processing unit calculates the ratio of the pulse difference value to the preset pulse value, namely the actual residual percentage.
In the above-described embodiments, the number of revolutions of the transmission shaft 93 and thus the number of revolutions of the pulley 91 and the stroke of the belt 92 can be calculated from the actual pulse value. By adopting the technical scheme, the actual remaining percentage of the cut tobacco 8 in the tobacco storage cabinet 1 is obtained by detecting the pulse number, the accuracy of the detected actual remaining 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 pieces 6 are uniformly distributed on the detection disk 61 around the axis of the detection disk 61, and the number of the metal pieces 6 is 12.
Further, the alarm mode comprises: whistling and/or flashing lights and/or displaying alarm information.
