Description

Technical Field

[0001] The utility model relates to the technical field related to cigarette production, and in particular to a two-dimensional code duplicate code comparison and screening system for multiple production lines and large amounts of data. Background Art

[0002] During the cigarette production process, box skins are generally processed and produced by printing factories, and traceability codes (barcodes or QR codes) are printed on the box skins. After that, they enter various cigarette factories. The QR codes on the box skins need to be collected before use. The existing collection production line includes a conveyor, a loading buffer mechanism located at the loading end of the conveyor for storing stacks of box skins, a paging mechanism for dividing the stacks of box skins into sheets and arranging them on the conveyor belt, a collection device located in the middle of the conveyor for collecting the traceability codes on the box skins, a collecting mechanism located at the output end of the conveyor for collecting the box skins into a fish-scale arrangement, a stacking mechanism for collecting the fish-scale arranged box skins into stacks, and a control device for controlling the operation of each mechanism. The traceability codes are collected and stored through this collection production line for traceability. However, various equipment problems or human factors during the printing process of box skins may cause duplicate codes. Due to the limited conditions of the printing factory and the large number of box skins, it is impossible to screen and identify them during the printing process, and the box skins with duplicate codes are sent to various cigarette factories. The existing collection equipment can only collect the traceability codes on the box skins, and cannot check the traceability codes for duplicates or exclude box skins with duplicate codes. As a result, the cigarette factories directly put box skins with duplicate codes into production during the production process, which brings certain problems to the management and traceability of the cigarette product circulation market. Utility Model Content

[0003] In order to overcome the existing technical defects, the purpose of the present invention is to provide a two-dimensional code duplicate code comparison and screening system for multiple production lines and large amounts of data to solve the above technical problems.

[0004] The technical solutions adopted by the present invention to solve the technical problems are as follows:

[0005] According to one aspect of the present invention, a multi-line, large-scale, two-dimensional code duplicate code comparison and screening system is designed, including a central server and several collection production lines, the collection production line including: a conveyor, a feeding buffer mechanism provided at one end of the conveyor, a paging mechanism, a collection device provided in the middle of the conveyor, a collection mechanism provided at the output end of the conveyor, a stacking mechanism, a rejection mechanism provided at the input end of the collection mechanism, and a control device, the conveyor including a frame and a first conveyor belt and a second conveyor belt provided on the frame, the top of the first conveyor belt is higher than the top of the second conveyor belt and is connected to the first conveyor belt. A gap is maintained between them, and the rejection mechanism is arranged at the gap position. The rejection mechanism includes a docking plate and a driving unit. The docking plate is inclined with the left lower and the right higher. The left end is docked with the second conveyor belt and rotates with the frame, and the right end is docked with the first conveyor belt. The rear end of the driving unit is hinged to the frame, and the driving end is connected to the docking plate to drive the docking plate to swing counterclockwise to form a blanking port between the first conveyor belt and the docking plate. The driving unit is communicatively connected to the control device, and each control device and collection device on the collection production line is communicatively connected to the central server.

[0006] With the above technical solution, when the QR code on the box skin needs to be collected before it is used in each cigarette factory, the stack of box skins will be placed on the loading buffer mechanism and transported to the paging mechanism. The paging mechanism will divide the stack of box skins into sheets and arrange them on the first conveyor belt to be transported to the left. When the box skin passes under the collection device, the traceability code on the box skin is collected by the collection device and transmitted to the central server. The central server is a conventional server with comparison and storage functions. The central server stores the received traceability code and compares it with all the traceability codes stored on it. If there is a duplicate code in the comparison result, the central server will feedback the information to the control device. When the box skin with the duplicate code is transported to the left end of the first conveyor belt, the control device controls the drive unit to start, and the drive unit drives the docking plate The counterclockwise swing forms a drop hole between the first conveyor belt and the docking plate, causing the box skins with duplicate codes to fall from the drop hole. Then the driving unit drives the docking plate to reset, and the normal box skins are output from the left end of the first conveyor belt and transported to the second conveyor belt through the docking plate and transported to the left. The box skins are collected into a fish-scale arrangement by the collecting mechanism. When the box skins are transported to the stacking mechanism, the fish-scale arranged box skins are collected into stacks by the stacking mechanism. The control devices on each collection production line are connected to the central server for communication, which can realize the comparison and detection of the traceability codes on the box skins on multiple production lines, and can eliminate the box skins with duplicate codes to prevent them from entering the packaging link and the finished product circulation link. When the finished cigarettes are circulated to the market, it is also convenient for management and tracing the source.

[0007] In order to better solve the above technical defects, the present invention also has a better technical solution:

[0008] In some embodiments, the rear end of the drive unit is hinged to the mounting base via a first hinge, the mounting base is fixed to the frame, a connecting block is fixed to the docking plate, the driving end of the drive unit is connected to a Y-shaped joint, and the connecting block and the Y-shaped joint are hinged via a second hinge.

[0009] In some embodiments, a connecting rod is connected to the left end of the docking plate, and the front and rear ends of the connecting rod are rotatably engaged with the connecting holes on the frame.

[0010] In some embodiments, a horizontal plate is provided at the right end of the docking plate, and the top surface of the horizontal plate is in the same plane as the top surface of the first conveyor belt or is lower than the height of the top surface of the first conveyor belt.
