Description

Technical Field

[0001] The utility model relates to the technical field of tobacco, in particular to a real-time statistical system for the number of semi-finished cigarettes in transit. Background Art

[0002] In cigarette production, cigarette manufacturers often need to change brands of production. There are two cigarette production modes in the packaging workshop. One is to determine the end time of production according to the total number of materials (the number of tobacco shreds), that is, to end production when the inventory of tobacco shreds is exhausted, to carry out the brand change process, and to prepare for the next brand production; the other is to determine the end time of production according to the planned quantity, that is, to end production when the planned number of finished products is reached, to carry out the brand change process, and to prepare for the next brand production. In the production mode according to the planned quantity, the number of finished products output must not be less than the planned quantity, and finished products exceeding the planned quantity need to be scrapped. In order to control costs and avoid material waste, factories usually need to accurately control the number of finished products.

[0003] In the cigarette production process of the rolling and packaging workshop, usually multiple equipments produce the same brand of finished products (the following text takes 4 equipments producing the same brand as an example). In the production process, there are semi-finished cigarettes, semi-finished cigarette boxes, semi-finished cigarette cartons, semi-finished cigarette stacks, etc., and the number of semi-finished products cached is relatively large. Because the number of semi-finished products in transit is unknown, in order to accurately control the final number of finished products, the factory usually conducts tail production when the planned quantity is about to be reached, that is, stop 3 equipments, keep 1 equipment to slow down production, and clear the semi-finished products in transit of 3 equipments; then determine the production volume of the last equipment according to the difference between the planned quantity and the actual production volume.

[0004] In the final production, due to the lack of real-time number of semi-finished products in transit, multiple devices need to be shut down, resulting in loss of equipment production capacity, which in turn increases the time for changing brands. In addition, under this production model, the number of semi-finished products in transit of the last device is still unknown, and the control of the number of finished products is too dependent on manual experience, making it difficult to manage and control.

[0005] In view of this, providing a real-time counting system for the number of semi-finished cigarettes in transit that can accurately count the number of semi-finished cigarettes in transit is a technical problem that needs to be solved urgently by those skilled in the art. Utility Model Content

[0032] In order to enable those skilled in the art to better understand the technical solutions in the utility model, the technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0033] like Figure 1 As shown, the embodiment of the utility model provides a real-time counting system for the number of semi-finished cigarettes in transit, comprising: a controller 1, and a first collector 2, a second collector 3 and a third collector 4 respectively connected to the controller 1;

[0034] The first collector 2 is used to collect statistics on the buffer capacity of semi-finished cigarettes in transit;

[0035] The second collector 3 is used to count the number of semi-finished cigarette rods in transit;

[0036] The third collector 4 is used to count the number of semi-finished cigarette stacks in transit;

[0037] The controller 1 is used for collecting in real time the semi-finished cigarette buffer capacity, the number of semi-finished cigarette rods in transit and the number of semi-finished cigarette stacks in transit collected by the first collector 2, the second collector 3 and the third collector 4 respectively.

[0038] In the actual application process, a controller and the first collector, the second collector and the third collector connected to the controller are set up; the first collector counts the cache capacity of the semi-finished cigarettes in transit, the second collector counts the number of semi-finished cigarettes in transit, and the third collector counts the number of semi-finished cigarettes in transit. Then the controller collects the number of semi-finished products in transit from the three collectors to the Siemens communication PLC centralized control system in real time through Siemens S7 communication, and the number of finished products to be produced is obtained by accumulating the number of finished products produced and the number of semi-finished products in transit. The planned number of finished products is then compared with the planned total amount, and the centralized control system suspends the equipment work order at the time of reaching production. The equipment work order is linked to the tobacco and filter rod conveying and supply pipelines. After the work order is suspended, the tobacco and filter rod conveying and supply pipelines are automatically closed to stop feeding the equipment.

[0039] By collecting and counting the number of semi-finished products in transit (cigarette sticks, cigarette cartons, and cigarette stacks) and the number of finished products in storage at each machine in real time, the number of semi-finished products in transit is converted into the number of finished products, and the difference between the planned quantity and the number of finished products is compared in real time. When the plan is completed (including semi-finished products in transit), the supply of cigarette materials is immediately stopped in combination with the production work order for the centralized control of rolling and packaging. After receiving the information, the operator can prepare for the brand change work. During the production process, since the number of semi-finished products in transit on the four devices is accurately known and converted into the number of finished products, with the help of this method, there is no need to stop the equipment and slow down the production to clear the cache, which greatly saves the time for tail production and releases the equipment capacity; and reduces the difficulty of manual control of production.

[0040] Preferably, the first collector is a cigarette buffer;

[0041] The cigarette buffer is wirelessly connected to the controller;

[0042] The cigarette buffer is used to count the buffer capacity of semi-finished cigarettes in transit.

[0043] In actual use, an S90 cigarette buffer is used to cache cigarettes. The S90 cigarette buffer is connected to the controller through a network, and reads the remaining capacity (percentage) of the cigarette cache in the cigarette buffer in real time. The remaining capacity of the cigarette cache is then transmitted to the controller through the OPC communication protocol. The controller converts the number of cigarette caches based on the remaining capacity of the cigarette cache.

[0044] Preferably, the second collector is a counting photoelectric tube;

[0045] The counting photoelectric tubes are respectively arranged at the entrance and exit of the cigarette conveying passage;

[0046] The counting photoelectric tube is used to count the number of cigarette rods.

[0047] In actual application, Figure 2 As shown in the figure (the photoelectric tube installation takes B01 unit as an example), the cigarette strips are transported to the stacker through the cigarette strip conveying channel, and then counting photoelectric tubes are installed at the entrance and exit of the cigarette strip conveying channel respectively. The counting photoelectric tube at the entrance of the cigarette strip conveying channel will generate a photoelectric tube signal, and the photoelectric tube signal at the entrance will be received by the central PLC of the controller, and the number of cigarette strips will be counted through the photoelectric tube signal.

[0048] Preferably, the counting phototube is a reflective phototube.

[0049] In actual use, the counting photoelectric tube adopts the common industrial reflective photoelectric tube and is installed on the tobacco rod conveying channel.

[0050] Preferably, the third collector is an RFID chip reader;

[0051] Install the RFID chip reader at the cigarette stack output outlet and the carton sealing machine entrance, and connect the signal line of the RFID chip reader to the cigarette stack conveying system PLC;

[0052] The RFID chip reader is used to collect RFID information on the cigarette stack mold box when the cigarette stack is conveyed to the box sealing machine.

[0053] In actual application, Figure 3 As shown in the figure (the reader installation takes B01 as an example), the semi-finished cigarette stacks are produced by the cigarette carton stacker, and the cigarette stacks (50 cigarettes per stack) are stacked in the mold box and output to the carton sealing machine through the cigarette stack conveying channel to be packaged as finished products; RFID chip readers are installed at the exit of the cigarette carton stacker and the entrance of the carton sealing machine, as shown in the figure. Figure 4 As shown in the figure (the reader installation takes No. 1 carton sealing machine as an example), the RFID chip reader is connected to the cigarette stack conveying system PLC, and the unique identification information of the cigarette stack is written into the RFID when the cigarette stack is produced, and the information cache area in the cigarette stack conveying system PLC is recorded; when the cigarette stack is conveyed to the carton sealing machine for sealing, the cigarette stack information is read by the RFID chip reader at the entrance of the carton sealing machine, and after reading the unique identification information, it is searched in the information cache area, and when the same information is found, it is deleted; in this way, the amount of information in the information cache area in the cigarette stack conveying system PLC is the number of semi-finished cigarette stacks in transit.

[0054] The third collector also provides an anti-human disturbance function. Since the cigarette stack conveying channel is long, there may be disturbances caused by human moving of cigarette stacks due to equipment failure or other factors. This will lead to differences in the number of semi-finished products in transit. The third collector will record the time when the cigarette stack information is generated. If the equipment is operating normally, the information of cigarette stacks that have not been sealed for a long time will be automatically cleared to ensure the accuracy of the number of semi-finished products in transit.

[0055] Preferably, the RFID chip reader is of model TNLR-Q80-H1147.

[0056] In actual use, the RFID chip is TURCK brand TW-R30-B128, installed at the bottom of the cigarette stacking mold box; the RFID reader is TURCK brand TNLR-Q80-H1147, installed at the cigarette stacking outlet of the stacker and the entrance of the carton sealing machine.

[0057] Preferably, the controller is a Siemens communication PLC centralized control system;

[0058] The Siemens communication PLC centralized control system is installed in an electrical control cabinet.

[0059] In actual use, the PLC is a Siemens S7-1500 series PLC centralized control system, which is installed in an electrical control cabinet close to the equipment work order. The planned number of finished products is obtained by accumulating the number of finished products produced and the number of semi-finished products in transit, and then the planned number of finished products is compared with the planned total amount. When the production capacity is reached, the Siemens communication PLC centralized control system will control the equipment work order to be suspended; there is a linkage relationship between the equipment production work order and the tobacco and filter rod conveying and supply pipelines. After the work order is suspended, the tobacco and filter rod conveying and supply pipelines are automatically closed to stop feeding the equipment.
