Description

Technical Field

[0001] This invention relates to the field of cigarette manufacturing, and more particularly to a full-process tobacco packing system involving the transmission of control information. Background Technology

[0002] With the rapid development of the tobacco industry, the technology of supplying tobacco from different locations has been widely used. In order to meet the needs of supplying tobacco from different locations, tobacco turnover boxes are used to transport tobacco.

[0003] The existing tobacco handling process requires first transporting the tobacco from the storage bins to the packing line, then removing the lids from the tobacco boxes and moving them to a designated location, where the tobacco is then loaded into a tobacco turnover box. Following this, operations such as capping, warehousing, warehousing, loading, and transportation are performed. This complete packing production line involves more than a dozen workstations. Therefore, developing a comprehensive packing system solution that includes full-process control and information transmission has become a pressing technical challenge in this field. Summary of the Invention

[0004] In view of the above, the present invention aims to provide a full-process tobacco packing system involving the transmission of control information, in order to solve the aforementioned technical problems.

[0011] The tobacco shred conveying equipment is connected to the tobacco shred pre-compression and boxing equipment and is located on one side of the conveying equipment at the boxing station;

[0012] The code sorting machine is located on one side of the box cover conveyor;

[0013] During the process of conveying cigarette boxes and lids, the conveying equipment transmits control information sequentially between several workstations in each conveying equipment. The control information includes at least one of the following: whether there is a task status, material type, target address of the material to be conveyed, weight, time, and equipment execution status.

[0014] In at least one possible implementation, the sequential transmission of control information between several workstations in each conveying device includes:

[0015] When the material is conveyed from the previous station to the next station in each conveying equipment, the next station changes from the initial information to the control information of the previous station.

[0016] Furthermore, after the material is conveyed from the previous station to the next station, the information of the previous station is reset to zero and cleared to the initial information.

[0017] In at least one of the possible implementations, the operation of the belt conveyor includes at least the following: after the belt conveyor at the previous station starts, the belt conveyor at the next station starts.

[0018] In at least one of the possible implementations, the operation of the chain conveyor includes at least the following: after the chain conveyor at the next station starts, the chain conveyor at the previous station starts.

[0019] In at least one possible implementation, the empty cigarette box conveying equipment further includes an empty box cleaning device consisting of a chain conveyor, a cleanliness detection mechanism, and a tilting and cleaning mechanism.

[0020] In at least one of the possible implementations:

[0021] The other end of the empty cigarette box conveying equipment is connected to one end of the packing station conveying equipment via a lifting and transferring machine.

[0022] The other end of the packing station conveyor is connected to one end of the solid cigarette box conveyor via a lifting and transferring machine.

[0023] The initial station of the empty cigarette box conveying equipment is connected to the empty box cleaning device via a lifting transfer machine.

[0024] Compared with the prior art, the main design concept of this invention is that one end of the empty cigarette box conveying equipment is connected to one end of the box lid conveying equipment via a gantry capping and decapping machine; the other end of the empty cigarette box conveying equipment is connected to one end of the box packing station conveying equipment; the other end of the box packing station conveying equipment is connected to one end of the full cigarette box conveying equipment; the other end of the full cigarette box conveying equipment is connected to the other end of the box lid conveying equipment via another gantry capping and decapping machine; the tobacco conveying equipment is connected to the tobacco pre-compression and box packing equipment and is located on one side of the box packing station conveying equipment; the sorting machine is located on one side of the box lid conveying equipment; during the conveying of cigarette boxes and box lids, the conveying equipment transmits control information sequentially between several station unit devices in each conveying equipment. This invention allows for the temporary storage of box lids on the packing production line, while the uncovered tobacco boxes enter the production line for weighing, tobacco filling, and other processes. Finally, the boxes are covered again at the end of the packing production line and sent out for storage. This process ensures that each link is connected in an orderly manner and that control information is linked, which can ensure that the packing production line has enough empty boxes to continuously fill with tobacco and ensure the continuity of production, thereby effectively improving packing efficiency. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described below with reference to the accompanying drawings, wherein:

[0026] Figure 1 A schematic diagram of a full-process tobacco packing system involving control information transmission provided for an embodiment of the present invention (the numbers in the diagram include the unit device numbers in each piece of equipment). Detailed Implementation

[0027] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0028] This invention proposes an embodiment of a full-process tobacco packing system involving control information transmission, specifically including: a system consisting of several units such as... Figure 1 The tobacco conveying equipment consisting of interconnected belt conveyors 1001, 1002, 1003, 1004, and 3001, wherein the automatic operation conditions of the belt conveyors 1001, 1002, 1003, 1004, and 3001 preferably simultaneously satisfy the following:

[0029] (1) The batch number of the selected storage tank is consistent with the order number issued by the manufacturing execution system (such as MES); (2) The selection signal of the selected storage tank is valid; (3) The metering tube is empty or has not reached the preset high material level.

[0030] In addition, it can be added that the operating rule of belt conveyors is that the subsequent motors start only after the preceding motors have started. Therefore, if the preceding motors fail, the subsequent motors will stop running.

[0031] Composed of several units, such as Figure 1 The empty smoke box conveying equipment consists of the chain conveyors 108, 109, 131, 110, 111, 113, and 115 connected to each other, and the lifting and transferring machines 130 and 114 located at the chain conveyors 109 and 115.

[0032] Composed of several units, such as Figure 1 The chain conveyors 118, 119, 120, and 121 connected in series form the packing station conveying equipment.

[0033] Depend on Figure 1 The shown is a tobacco pre-compression and boxing equipment consisting of a reciprocating fabric cart 3003, a pressing device 116, and an electronic scale 3002.

[0034] Composed of several units, such as Figure 1 The chain conveyors 123, 122, 124, 125, 126, 128, and 129 shown constitute the solid smoke box conveying equipment.

[0035] Composed of several units, such as Figure 1 The chain conveyors 102, 104, 103, and 106 shown constitute the box cover conveying equipment.

[0036] As Figure 1 The box lid processing equipment shown consists of the gantry cap removal machine 101, the gantry cap removal machine 107, and the code sorting machine 105 (also known as the follow-up code sorting machine or box lid lifting and storage device).

[0037] First, after the packing system is started, the tobacco in the storage cabinet reaches the metering tube via a belt conveyor, pre-fills the electronic scale, and fills the metering tube, waiting for the tobacco box to arrive;

[0038] To elaborate on this, the batch number information of the selected storage cabinet is compared with the work order information of the production execution system. When the order number information matches, the corresponding finished tobacco storage cabinet and the conveying equipment between the storage cabinet and the pre-compression and packing equipment are started. After the finished tobacco reaches the packing area through the conveying equipment, the system starts the tobacco packing and pre-compression operation according to the process parameters.

[0039] Secondly, after the packing system is started, it continuously and stably supplies the tobacco boxes to be packed. Based on the information on the load, it issues instructions. The tobacco boxes to be packed reach the cap removal station. The cap removal device removes the caps from the tobacco boxes. The tobacco boxes to be packed enter the cleanliness detection station. The tobacco boxes to be packed (empty boxes) that need to be cleaned enter the cleaning station for automatic cleaning and then return to the cleanliness detection station. They are then sent to the weighing station for tobacco boxes to be packed. After being weighed, they are transferred to the next process.

[0040] To elaborate on this, after the tobacco box automatically enters and reaches the designated initial position, the packing system automatically generates tobacco box information. The lid removal device automatically grabs the lid and places it on a fixed translation device. Simultaneously, lid information is automatically generated. Once the packing system determines that the lid is in place, it automatically transports it to a preset position. During this process, the lid-adding station maintains a state with the lid and its information. If the conveyor is not full, a lid-filling operation is automatically performed, and the lid is automatically stored in the lid lifting and storage device. More preferably, during the production process, if there is a spare station between the lid lifting and storage device and the lid-adding station, the lid lifting and storage device automatically releases the lid to replenish the corresponding spare station. After the tobacco box is decapped, it automatically moves to the next preset station. The imaging device determines whether the tobacco box is clean and decides whether to enter the cleaning device based on the judgment result. For tobacco boxes that need to be cleaned, they return to the original station after cleaning and then move to the next station. When the tobacco box moves to the weighing station, it automatically weighs the tobacco box and determines whether the box is empty or half-full, and records the corresponding weight value into the tobacco box station information.

[0041] Then, after the tobacco box is filled with a predetermined amount of tobacco in the packing area, it is sent to the weighing station. The weighing system weighs the total weight of the box. After weighing, it is sent to the capping station. The capping and uncapping mechanism puts the cap on the box. After the cap is put on, the tobacco box carries information such as the actual weight of the tobacco, the tobacco production batch information, and the packing time, and transmits the information to the production execution system.

[0042] Finally, the covered cigarette boxes are sent to the warehousing system.

[0043] Throughout the entire process of receiving boxes, removing lids, conveying, cleaning, weighing, loading, capping, and warehousing, the lids and tobacco boxes are verified at each workstation, platform, device, and area to ensure the correct tobacco box information. Furthermore, once a lid or tobacco box leaves its current position, the information recorded at that position is automatically reset to zero, ensuring that information for newly arriving lids or tobacco boxes continues to be entered. In addition, lids are automatically added to and removed from the lid lifting and storage device, and the corresponding quantity data is recorded.

[0044] The following section will provide a detailed description of the control and information transmission implementation methods of the present invention, with reference to the accompanying drawings.

[0045] For details regarding the information transmission and control methods between empty smoke box conveying equipment, please refer to the following:

[0046] (1) As shown in the figure, the initial chain conveyor 108 is used as the following example (after the gantry cap remover 101 has removed the box caps and placed them on the chain conveyor 102 of the box cap conveying equipment):

[0047] When the batch number of the storage container selected by the packing system matches the order number issued by the manufacturing execution system, the motor of the chain conveyor 108 is triggered to run. When the material signal of the chain conveyor 108 is 1 (in... Figure 1 In the example, the corresponding signal dot for station 108 is lit up, the information task number of chain conveyor 108 changes from "0" to "99999" (indicating that there is a task, the same below), and the target address changes from "0" to "109" (the address of the next device), and the pneumatic baffle of chain conveyor 108 (shown by the thick line below 108 in the figure, the same below will not be repeated) retracts. At this point, the material type of the chain conveyor 108 changes from "no smoke box" to "empty smoke box" / "half box" (determined according to the material type of the preceding smoke box of the chain conveyor 108; since the chain conveyor 108 is the initial stage in this example, its preceding stage is not shown). For example, if the material type of the preceding smoke box of the chain conveyor 108 is half box (it should be noted that half box does not refer to an absolute 1 / 2, but only indicates that the smoke box is not empty and contains a certain amount of tobacco), then the gross weight of the smoke box changes from "0" to the gross weight value of the preceding smoke box of the chain conveyor 108, and the net weight of the smoke box changes from "0" to the net weight value of the preceding smoke box of the chain conveyor 108. It can be added that the setting of material type information can be referenced as follows: no smoke box is 0, empty smoke box is 1, full smoke box is 2, and half box is 3.

[0048] The chain conveyor 108 operates under any one of the following conditions:

[0049] First, the inbound and outbound system has empty boxes supplied, the number of cigarette boxes in the packing system is less than the predetermined number (8), the chain conveyor 108 has no task, and there is no material on the chain conveyor 108.

[0050] Second, chain conveyor 108 has a task, the target address is "109", the lifting motor of the lifting transfer machine 130 has descended to the position, chain conveyor 109 has no task, the motor of chain conveyor 109 has no fault, and there is no material on the chain conveyor of chain conveyor 109.

[0051] (2) Chain conveyor 109:

[0052] When the motor of chain conveyor 108 starts running, the motor of the next chain conveyor 109 also starts running. When the material signal dot of chain conveyor 109 is lit, the information task number of chain conveyor 109 changes from "0" to "99999", the material type changes from "no smoke box" to "empty smoke box" / "half box" (determined according to the smoke box material type of chain conveyor 108), the gross weight of the smoke box of chain conveyor 109 changes from "0" to the gross weight value of the smoke box of chain conveyor 108, and the net weight of the smoke box changes from "0" to the net weight value of the smoke box of chain conveyor 108; and chain conveyor 109 pauses the cleaning judgment.

[0053] At the same time, the information task number of the preceding chain conveyor 108 changes from "99999" to "0", the material type changes from "empty smoke box" / "half box" to "no smoke box", the target address changes from "109" to "0", the gross weight of the smoke box changes to "0", the net weight of the smoke box changes to "0", and the motor pauses until the next smoke box arrives at the work station. This process is referred to as reset and zeroing in the following text.

[0054] Continuing from the previous text, if the material type of the chain conveyor 109 is a half-box, then the cleanliness of the smoke box is not checked, and the target address of the chain conveyor 109 changes from "0" to "110". If the material type of the chain conveyor 109 is an empty smoke box, then the cleanliness of the smoke box is checked. When the smoke box cleanliness detection equipment (visual inspection can be used) has completed the inspection, if the detection result is in line with the established cleanliness standard, then no cleaning is required. At this time, the target address of the chain conveyor 109 changes from "0" to the next chain conveyor "110". If the detection result indicates that the cleanliness of the smoke box does not meet the standard, then cleaning is required. At this time, the target address of the chain conveyor 109 changes from "0" to "130".

[0055] The chain conveyor 109 operates under any one of the following conditions:

[0056] First, the chain conveyor 108 has a task, the target address is "109", the lifting motor of the lifting transfer machine 130 has descended to the position, the chain conveyor 109 has no task, the motor of the chain conveyor 109 has no fault, and there is no material on the chain conveyor of the chain conveyor 109.

[0057] Second, the chain conveyor 109 has a task, the target address is "110", the lifting motor of the lifting transfer machine 130 has descended to the position, the chain conveyor 110 has no task, the motor of the chain conveyor 110 is not faulty, and there is no material on the chain conveyor of the chain conveyor 110.

[0058] (3) Lifting and transferring machine 130:

[0059] If the target address of the chain conveyor 109 is "130", the lifting transfer machine 130 (via its lifting motor, the same below will not be described in detail) rises to the position, the information task number of the lifting transfer machine 130 changes from "0" to "99999", the material type changes from "smokeless box" to "empty smoke box", and the target address changes from "0" to "131"; at this time, the information task number, material type and target address of the chain conveyor 109 are all reset to zero.

[0060] The operating conditions of the lifting motor of the jacking and transferring machine 130 meet any of the following conditions:

[0061] Ascending: The lifting motor is in a low position, the lifting transfer machine 130 has no task, the chain conveyor 109 has a task, and the target address of the chain conveyor 109 is "130";

[0062] Lowering: The lifting motor is in a high position, and the lifting transfer machine 130 is not under any task;

[0063] Descent: The lifting motor is in a high position, the lifting transfer machine 130 has a task, and the target address is "109".

[0064] The operating conditions of the transfer motor of the lifting transfer machine 130 meet any of the following conditions:

[0065] Forward rotation: The lifting motor has reached the position, the lifting transfer machine 130 has a task, the target address of the lifting transfer machine 130 is "131", the chain conveyor 131 has no task, the motor of the chain conveyor 131 is fault-free, and there is no material on the chain conveyor of the chain conveyor 131.

[0066] Reversal: The lifting motor has risen to the correct position, the chain conveyor 131 has a task, the target address of the chain conveyor 131 is "130", the lifting transfer machine 130 has no task, the motor of the lifting transfer machine 130 is not faulty, and there is no material on the lifting transfer machine 130.

[0067] (4) Chain conveyor 131:

[0068] The lifting and transferring machine 130 (including the transfer motor, which will not be described in detail below) runs in the forward direction, and the motor of the chain conveyor 131 runs in the forward direction. When the material signal dot of the chain conveyor 131 is lit, the information task number of the chain conveyor 131 changes from "0" to "99999", the material type changes from "no smoke box" to "empty smoke box", and the target address changes from "0" to "131".

[0069] The information task number, material type, and target address of the lifting and transferring machine 130 are all reset to zero; the box-turning and cleaning equipment located at the chain conveyor 131 starts to operate; after the box-turning and cleaning is completed, the cigarette box is put back on the chain conveyor 131, at which time the target address of the chain conveyor 131 changes from "131" to "130".

[0070] The motor of the chain conveyor 131 runs in reverse, and the lifting and transferring machine 130 runs in reverse. When the material signal dot of the lifting and transferring machine 130 is lit, the information task number of the lifting and transferring machine 130 changes from "0" to "99999", the material type changes from "no smoke box" to "empty smoke box", and the target address changes from "0" to "109". Simultaneously, the information task number, material type, and target address of the chain conveyor 131 are all reset to zero.

[0071] When the lifting transfer machine 130 descends to its position, the information task number of the chain conveyor 109 changes from "0" to "99999", the material type changes from "no smoke box" to "empty smoke box", and the target address changes from "0" to "110"; the information task number, material type, and target address of the lifting transfer machine 130 are all reset to zero.

[0072] (5) Chain conveyor 110:

[0073] Unlike belt conveyors, except for the initial 108 to 109, the other chain conveyors are started by the subsequent motors, and then the preceding motors are started. That is, after chain conveyor 110 is running, it indicates that chain conveyor 110 is ready to receive. At this time, the motor of chain conveyor 109 runs to transport the cigarette box to 110. When the cigarette box arrives at 110, it stops briefly and checks whether chain conveyor 111 has been triggered to run (it can be triggered by conditions such as a change in the target address, which will be explained later).

[0074] In detail, when the material signal dot of chain conveyor 110 is lit, the information task number of chain conveyor 110 changes from "0" to "99999", the material type changes from "no smoke box" to "empty smoke box" / "half box" (determined according to the material type of smoke box of chain conveyor 109), the target address changes from "0" to "111", the gross weight of smoke box of chain conveyor 110 changes from "0" to the gross weight value of smoke box of chain conveyor 109, and the net weight of smoke box changes from "0" to the net weight value of smoke box of chain conveyor 109; simultaneously, the information task number, material type, target address, and gross and net weight of smoke box of chain conveyor 109 are all reset to zero.

[0075] (6) Chain conveyor 111:

[0076] When the motors of chain conveyors 111 and 110 are running, and the material signal dot of chain conveyor 111 is lit, the information task number of chain conveyor 111 changes from "0" to "99999", the material type changes from "no smoke box" to "empty smoke box" / "half box" (determined according to the material type of the smoke box of chain conveyor 110), the gross weight of the smoke box of chain conveyor 111 changes from "0" to the gross weight value of the smoke box of chain conveyor 110, and the net weight of the smoke box changes from "0" to the net weight value of the smoke box of chain conveyor 110. Simultaneously, the information task number, material type, target address, and gross and net weight of the smoke box of chain conveyor 110 are all reset to zero.

[0077] If the material type of the chain conveyor 111 is an empty cigarette box, the weighing is completed by the weighbridge 112 located here. The gross weight of the cigarette box of the chain conveyor 111 becomes the actual empty box weight value (excluding the box cover). When the condition that the gross weight of the empty box of the chain conveyor 111 is less than the abnormal empty box weight is met, the target address of the chain conveyor 111 changes from "0" to "113", and the pneumatic baffle of the chain conveyor 111 retracts. If the gross weight of the empty box of the chain conveyor 111 is greater than the abnormal empty box weight, an alarm is output to indicate that the empty box weight is abnormal.

[0078] If the material type of chain conveyor 111 is half a box, the weighing is completed by the weighbridge 112 located here, and the following condition is calculated: |Net weight of the tobacco box of chain conveyor 111 - Actual net weight of the tobacco box obtained by weighing on the weighbridge 112| < Abnormal half-box tobacco weight deviation value. If this condition is met, the target address of chain conveyor 111 changes from "0" to "113", and the pneumatic baffle of chain conveyor 111 retracts. Conversely, if |Net weight of the tobacco box of chain conveyor 111 - Actual net weight of the tobacco box obtained by weighing on the weighbridge 112| ≥ Abnormal half-box tobacco weight deviation value, an alarm is output indicating a fault "Abnormal half-box weight".

[0079] (7) Chain conveyor 113:

[0080] When the motor of chain conveyor 113 and chain conveyor 111 are running, and the material signal dot of chain conveyor 113 is lit, the information task number of chain conveyor 113 changes from "0" to "99999", the material type changes from "no smoke box" to "empty smoke box" / "half box" (determined according to the material type of the smoke box of chain conveyor 111), the target address changes from "0" to "114", the gross weight of the smoke box changes from "0" to the gross weight value of the smoke box of chain conveyor 111, and the net weight of the smoke box changes from "0" to the net weight value of the smoke box of chain conveyor 111; chain conveyor 111 is reset to zero.

[0081] (8) Lifting and transferring machine 114:

[0082] The transfer motor of the lifting transfer machine 114 and the motor of the chain conveyor 113 are running. When the material signal dot of the lifting transfer machine 114 is lit, the information task number of the lifting transfer machine 114 changes from "0" to "99999", the material type changes from "no smoke box" to "empty smoke box" / "half box" (determined according to the material type of the smoke box of the chain conveyor 113), the target address changes from "0" to "115", the gross weight of the smoke box changes from "0" to the gross weight value of the smoke box of the chain conveyor 113, and the net weight of the smoke box changes from "0" to the net weight value of the smoke box of the chain conveyor 113; the chain conveyor 113 is reset to zero.

[0083] (9) Chain conveyor 115:

[0084] The lifting motor of the jacking and transferring machine 114 descends to its position, and the motor of the chain conveyor 115 starts running. When the material signal dot of the chain conveyor 115 lights up, the information task number of the chain conveyor 115 changes from "0" to "99999", the material type changes from "no smoke box" to "empty smoke box" / "half box" (determined according to the material type of the smoke box of the jacking and transferring machine 114), the target address changes from "0" to "118", the gross weight of the smoke box changes from "0" to the gross weight value of the smoke box of the jacking and transferring machine 114, and the net weight of the smoke box changes from "0" to the net weight value of the smoke box of the jacking and transferring machine 114; the jacking and transferring machine 114 is reset to zero.
