Description

Technical Field

[0001] This invention discloses a product information transmission system and method in a polycrystalline silicon packaging system, belonging to the field of packaging machinery. Background Technology

[0002] Patent documents CN210437431U, CN112389754A, and CN112407372A disclose an automatic weighing device for polycrystalline silicon, a rotary primary packaging device, and a secondary bagging device, respectively. These three devices together constitute a polycrystalline silicon packaging system. With the increase in the variety of polycrystalline silicon products, different products need to be packaged within the same system, and these products also need to be packaged alternately online simultaneously. However, due to product cleanliness requirements, labels or coding cannot be affixed to the primary packaging bags. Consequently, the labels affixed to the secondary bagging bags cannot correspond to the product information, and the label information cannot fully describe the product type, specifications, net weight, batch number, and other information of the products inside the bag. Summary of the Invention

[0003] To address the problem that labels affixed to secondary outer bags in existing polysilicon packaging systems cannot fully describe the detailed information of the products inside, this invention proposes a product information transmission system and method for polysilicon packaging systems. The product information transmission system includes a host computer system, a PLC system, an RFID reader / writer, RFID electronic tags, a full-box weighing unit, and an empty-box weighing unit. The host computer system receives initial product information from the factory's MES system and forwards it to the PLC system. Simultaneously, the host computer system receives complete product information from the PLC system and uploads it to the MES system. The PLC system receives detection signals from field sensors and controls... The system determines the sequence of actions of each mechanism in the polysilicon packaging system. Simultaneously, the PLC system controls the reading and writing actions of the RFID reader and exchanges data with it. The RFID reader reads and writes information into the RFID electronic tags. The RFID electronic tags are affixed to the side of each turnover box within the polysilicon primary packaging unit. The full-box weighing unit weighs the total weight of the bags and turnover boxes after primary packaging and uploads the total weight data to the PLC system. The empty-box weighing unit weighs the empty turnover boxes before they enter the bag unloading position of the primary packaging device and uploads the box weight data to the PLC system. The transmission method based on the product information transmission system includes the following processes:

[0004] (1) The MES system sends the initial product information to the host computer system. The initial product information includes the product type and batch number.

[0005] (2) The host computer system sends the initial product information to the PLC system;

[0006] (3) The PLC system determines the main material to be weighed and its storage hopper number based on the polysilicon level signal in each storage hopper above the automatic weighing device that stores large, medium and small materials. The PLC system adds this storage hopper number as the product specification to the product information of the product being weighed, forming intermediate product information: variety, batch number and specification.

[0007] (4) After the automatic weighing device completes the weighing, the material is unloaded into the discharge cylinder of the rotary one-time packaging device. The PLC system records the intermediate information of the product corresponding to the discharge cylinder number.

[0008] (5) After the material drop cylinder rotates to the unloading station, the PLC system transmits the intermediate information of the product in the corresponding numbered material drop cylinder to the first RFID reader on the unloading conveyor. The first RFID reader writes the intermediate information of the product into the RFID electronic tag of the turnover box on the unloading conveyor.

[0009] (6) After the full box is transported to the full box weighing unit, the full box weighing unit uploads the total weight data to the PLC system. At the same time, the second RFID reader on the full box weighing unit reads the box weight data in the RFID electronic tag and uploads it to the PLC system. The PLC system calculates the net weight of the product and sends it to the second RFID reader. The second RFID reader writes the final product information into the RFID electronic tag on the turnover box, including the variety, batch number, specifications, and net weight.

[0010] (7) The full box is transported to the bag transfer machine of the primary packaging device. While the bag transfer mechanism grabs the bag, the third RFID reader on the bag transfer machine reads the final product information in the RFID electronic tag and transmits it to the PLC system. The PLC system adds a serial number to the final product information to form complete product information and sends it to the label printer and host computer system in the secondary bagging device. The label printer prints a label containing complete product information. The labeling machine pastes this label on the outer surface of the secondary bagging packaging bag. The PLC system controls the sequence of actions of the mechanism in the secondary bagging device to ensure that the label information of the outer bag is completely consistent with the polysilicon product in the primary bag packed into the outer bag.

[0011] (8) After the empty container returned from the low position is transported to the empty container weighing unit, the empty container weighing unit uploads the container weight data to the PLC system. The PLC system sends the container weight data to the fourth RFID reader on the empty container weighing unit. The fourth RFID reader writes the container weight data into the RFID electronic tag on the container.

[0012] The beneficial effects of this invention are: by using RFID electronic tags on turnover boxes as intermediate carriers of product information, and through data interaction between multiple information subsystems, the complete product information of polysilicon in the primary packaging bag is accurately transmitted to the paper label on the secondary packaging outer bag. At the same time, it also realizes flexible production of the entire polysilicon packaging system, which can simultaneously and alternately package products of different varieties, batch numbers and specifications, providing technical support for the automation, informatization and intelligent production and management of enterprises.

The product information transmission system includes a host computer system, a PLC system, an RFID reader / writer, RFID electronic tags, a full-box weighing unit, and an empty-box weighing unit. The host computer system receives initial product information sent by the factory's MES system and forwards it to the PLC system. Simultaneously, the host computer system receives complete product information sent by the PLC system and uploads it to the MES system. The PLC system receives detection signals from field sensors and controls the action sequence of various mechanisms in the polysilicon packaging system. The PLC system also controls the reading and writing actions of the RFID reader / writer and exchanges data with it. The RFID reader / writer reads and writes information into the RFID electronic tags, which are affixed to the side of each turnover box within the polysilicon primary packaging unit. The full-box weighing unit weighs the total weight of the bags and turnover boxes after primary packaging and uploads the total weight data to the PLC system. The empty-box weighing unit weighs the empty turnover boxes before they enter the bag unloading position of the primary packaging device and uploads the box weight data to the PLC system. The transmission method based on the product information transmission system includes the following processes:

[0015] (1) The MES system sends the initial product information to the host computer system. The initial product information includes the product type and batch number.

[0016] (2) The host computer system sends the initial product information to the PLC system;

[0017] (3) The PLC system determines the main material to be weighed and its storage hopper number based on the polysilicon level signal in each storage hopper above the automatic weighing device that stores large, medium and small materials. The PLC system adds this storage hopper number as the product specification to the product information of the product being weighed, forming intermediate product information: variety, batch number and specification.

[0018] (4) After the automatic weighing device completes the weighing, the material is unloaded into the discharge cylinder of the rotary one-time packaging device. The PLC system records the intermediate information of the product corresponding to the discharge cylinder number.

[0019] (5) After the material drop cylinder rotates to the unloading station, the PLC system transmits the intermediate information of the product in the corresponding numbered material drop cylinder to the first RFID reader on the unloading conveyor. The first RFID reader writes the intermediate information of the product into the RFID electronic tag of the turnover box on the unloading conveyor.

[0020] (6) After the full box is transported to the full box weighing unit, the full box weighing unit uploads the total weight data to the PLC system. At the same time, the second RFID reader on the full box weighing unit reads the box weight data in the RFID electronic tag and uploads it to the PLC system. The PLC system calculates the net weight of the product and sends it to the second RFID reader. The second RFID reader writes the final product information into the RFID electronic tag on the turnover box, including the variety, batch number, specifications, and net weight.

[0021] (7) The full box is transported to the bag transfer machine of the primary packaging device. While the bag transfer mechanism grabs the bag, the third RFID reader on the bag transfer machine reads the final product information in the RFID electronic tag and transmits it to the PLC system. The PLC system adds a serial number to the final product information to form complete product information and sends it to the label printer and host computer system in the secondary bagging device. The label printer prints a label containing complete product information. The labeling machine pastes this label on the outer surface of the secondary bagging packaging bag. The PLC system controls the sequence of actions of the mechanism in the secondary bagging device to ensure that the label information of the outer bag is completely consistent with the polysilicon product in the primary bag packed into the outer bag.

[0022] (8) After the empty container returned from the low position is transported to the empty container weighing unit, the empty container weighing unit uploads the container weight data to the PLC system. The PLC system sends the container weight data to the fourth RFID reader on the empty container weighing unit. The fourth RFID reader writes the container weight data into the RFID electronic tag on the container.
