Description

Technical Field

[0001] This invention relates to a method for tracking tobacco package information, and more particularly to a method for tracking tobacco package information in a continuous tobacco package rehydration production line. Background Technology

[0002] In the continuous production process of the vacuum rehumidification pretreatment section, the outer packaging of individual 200kg (40 packs / batch) cardboard cigarette packs, which are released from the raw material warehouse according to the formula sequence and carry information, is removed by the cigarette pack opening system, turning them into naked packs. These naked packs are then conveyed into metal frames via a conveyor device. Individual full cigarette boxes enter the vacuum rehumidification machine in the order before unpacking. Through vacuuming, vacuum breaking, heating, and humidification, impurities are removed. The boxes are then turned over and unpacked according to the first-in-first-out order. Loose materials enter the next processing stage and are processed in modules one, two, and three. In terms of cigarette pack form, there are three types: cardboard cigarette packs, naked packs, and full cigarette boxes. By designing coding rules and data storage and query methods, the transmission and tracking of cigarette pack information can be achieved regardless of the cigarette pack form. This provides technical support for subsequent switching of loose rehumidification group processing parameters according to cigarette pack weight and for the module-by-module formula call of the impurity sorting machine. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a method for tracking tobacco pack information in a continuous tobacco pack rehydration production line.

[0004] To achieve the purpose of this invention, the following technical solution is adopted:

[0005] This invention discloses a method for tracking cigarette pack information in a continuous cigarette pack rehydration production line. The cigarette pack rehydration production line includes: a pack opening machine, a case packing machine, a slicer, a distributor, a first vacuum rehydration machine, a second vacuum rehydration machine, a case turning and unloading machine, and a controller. The pack opening machine, case packing machine, slicer, and distributor are connected sequentially. The first and second vacuum rehydration machines are connected in parallel. Their inlets are connected to the distributor, and their outlets are connected to the case turning and unloading machine. The controller is connected to the pack opening machine, case packing machine, slicer, distributor, first vacuum rehydration machine, second vacuum rehydration machine, and case turning and unloading machine. The above devices are interconnected via conveyor belts. A first counter is arranged at the inlet of the pack opening machine. At least one first phototube is arranged on the conveyor belt between the pack opening machine and the case packing machine. On the conveyor belt between the case packing machine and the slicer... At least one second phototube is arranged; at least one third phototube is arranged on the conveyor belt between the slicer and the distributor; at least one fourth phototube and at least one fifth phototube are arranged on the conveyor belts between the distributor and the first vacuum rehumidifier, and between the distributor and the second vacuum rehumidifier, respectively; at least one sixth phototube or a seventh phototube is arranged on the conveyor belts between the box-turning and unloading machine and the first vacuum rehumidifier, and between the box-turning and unloading machine and the second vacuum rehumidifier, respectively; a third counter and a fourth counter are arranged at the entrance of the first vacuum rehumidifier and the entrance of the second vacuum rehumidifier, respectively; and a fifth counter is arranged at the entrance of the cigarette box of the box-turning and unloading machine. All the above counters and phototubes are connected to a controller. The cigarette box information tracking method in the continuous cigarette box rehumidification production line includes the following steps:

[0006] (i) When the cigarette pack enters the continuous cigarette pack re-moistening production line, the first counter starts counting, the pack opener obtains the cigarette pack information, the first counter and the pack opener transmit the count and cigarette pack information to the pack opener information storage area of ​​the controller, the pack opener performs the pack opener process, and then the pack opener transmits the cigarette pack to the case packer via the conveyor belt.

[0007] (ii) When all the first phototubes send a trigger signal to the controller, the cigarette packs are transported to the packing machine via the conveyor belt. The controller will send the cigarette pack information stored in the packing machine information storage area to the packing machine information storage area. The packing machine will pack the cigarette packs to obtain a full cigarette box, and then transport the full cigarette box to the slicer via the conveyor belt.

[0008] (iii) When all the second phototubes send a trigger signal to the controller, the above-mentioned cigarette box is transported to the slicer via the conveyor belt. The controller will send the cigarette pack information stored in the packing machine information storage area to the slicer information storage area. After the slicer slices the tobacco leaves in the cigarette box, it will then transport the cigarette box to the distributor via the conveyor belt.

[0009] (iv) When all the third phototubes send a trigger signal to the controller, the above-mentioned cigarette box is transported to the distributor via the conveyor belt. The controller will transport the cigarette pack information stored in the slicer information storage area to the distributor information storage area. The distributor will then transport the cigarette box to the first vacuum rehumidifier or the second vacuum rehumidifier via the conveyor belt.

[0010] (v) When all the fourth phototubes send a trigger signal to the controller, the above-mentioned tobacco boxes are transported to the first vacuum rehumidifier via the conveyor belt. The controller will send the tobacco package information stored in the information storage area of ​​the distributor to the information storage area of ​​the first vacuum rehumidifier. The third counter starts counting the tobacco boxes entering the first vacuum rehumidifier. When the number of tobacco boxes entering the first vacuum rehumidifier reaches the set number of tobacco boxes, the first vacuum rehumidifier performs vacuum rehumidification on the tobacco leaves in the above-mentioned tobacco boxes, and then the above-mentioned tobacco boxes are transported to the box turning and unloading machine via the conveyor belt.

[0011] Or (vi) When all the fifth phototubes send a trigger signal to the controller, the above-mentioned tobacco boxes are transported to the second vacuum rehumidifier via a conveyor belt. The controller will send the tobacco package information stored in the information storage area of ​​the distributor to the information storage area of ​​the second vacuum rehumidifier. The fourth counter starts counting the tobacco boxes entering the second vacuum rehumidifier. When the number of tobacco boxes entering the second vacuum rehumidifier reaches the set number of tobacco boxes, the second vacuum rehumidifier performs vacuum rehumidification on the tobacco leaves in the above-mentioned tobacco boxes, and then the above-mentioned tobacco boxes are transported to the box turning and unloading machine via a conveyor belt.

[0012] (vii) When all the sixth phototubes or all the seventh phototubes send a trigger signal to the controller, the above-mentioned solid cigarette box is transported to the box-turning and unloading machine by the conveyor belt. The controller will send the information of the cigarette pack stored in the information storage area of ​​the first vacuum rehumidifier or the second vacuum rehumidifier to the information storage area of ​​the box-turning and unloading machine. After the box-turning and unloading machine performs the box-turning and unloading process on the solid cigarette box, the loose cigarette is processed and the empty cigarette box enters the empty box buffer channel for later use.

[0013] (viii) The fifth counter counts the actual cigarette boxes entering the inlet of the turning and unloading machine. When the number of actual cigarette boxes reaches the predetermined number of cigarette boxes for this batch, the continuous cigarette pack rehydration production line completes the processing of this batch of cigarette packs.

[0014] The present invention discloses a method for tracking cigarette pack information in a continuous cigarette pack rehydration production line, wherein: when a phototube on a certain conveyor belt fails to send a trigger signal to the controller within a predetermined time, a malfunction occurs in the continuous cigarette pack rehydration production line. The operator checks the cigarette pack information in the information storage area of ​​the unpacking machine, packing machine, slicing machine, distributing machine, first vacuum rehydration machine, second vacuum rehydration machine or box turning and unloading machine stored in the controller to determine the information of the cigarette packs being produced in the continuous cigarette pack rehydration production line and the cigarette pack count in this batch.

[0015] The present invention discloses a method for tracking tobacco package information in a continuous tobacco package rehydration production line, wherein there are 2-5 photocells on a certain conveyor belt.

[0016] The present invention discloses a method for tracking tobacco package information in a continuous tobacco package rehydration production line, wherein a second counter is arranged on the conveyor belt between the packing machine and the slicing machine, and the second counter is connected to a controller.

[0017] The present invention discloses a method for tracking tobacco package information in a continuous tobacco package rehydration production line, wherein the tobacco package information includes: formula number, tobacco package serial number, and tobacco package weight.

[0018] This invention discloses a method for tracking cigarette pack information in a continuous cigarette pack rehydration production line. This method utilizes logic control between the conveyor belt and photocells, and encodes the devices to accurately transmit cigarette pack information to the next device. The controller contains storage areas for each device. This method is simple and practical, and the equipment used is economical and environmentally friendly. It effectively transmits cigarette pack information accurately level by level. During material conveying control, the method adds cigarette pack counting and sequential transmission of cigarette pack information, ensuring the integrity of batches and preventing mismatches caused by overlapping batches. It also enables group processing of subsequent vacuum rehydration and loose rehydration. This method has extremely wide applications in tracking and controlling tobacco processing material information and preventing errors.

[0019] The controller of this invention is also equipped with a monitoring and display function. When multiple devices are producing continuously, multiple work order information tracks the movement of materials and can view the identity information of cigarette packs in real time. The system automatically determines whether the set number has been reached based on the identity information of the cigarette packs and the total count. If the actual number of packs is not equal to the set number of packs, the end of the batch is prohibited. This successfully avoids the "tail-end" between two consecutive batches, ensuring the rationality of continuous production and the traceability of quality. Attached Figure Description
