Description

Technical Field

[0001] This utility model relates to a device for standardizing the feeding of materials by operators and preventing errors, specifically addressing the safety hazards that employees may encounter when unpacking carbon black and eliminating the quality risk of incorrect carbon black feeding. Background Technology

[0002] Rubber mixing is a key process in tire manufacturing, which mainly involves mixing various raw materials and rubber to form rubber sheets of various specifications used in subsequent processes.

[0003] Technical Issue 1: When employees unpack carbon black, they need to use a crane to lift the carbon black ton bags onto the daily storage hopper. The personnel unpack the carbon black ton bags while they are suspended in the air. When the crane slides down or the ton bag lifting strap slips off, it can cause serious safety accidents.

[0004] Technical Issue 2: Carbon black is an essential raw material in tire manufacturing. There are numerous types and manufacturers of carbon black, and the daily carbon black storage hoppers lack error-proofing devices, posing a quality risk of carbon black being mishandled. Due to the special nature of the rubber mixing process, mishandling carbon black can result in batches of substandard rubber compounds, leading to significant cost losses. Utility Model Content

[0005] The purpose of this invention is to provide a device to standardize the feeding of materials by operators and prevent errors, so as to solve the above two problems.

[0006] The specific technical solution of this utility model is as follows: A device for preventing incorrect material feeding by standardized operators includes a carbon black storage platform with a discharge port. A valve plate is located below the discharge port and can slide horizontally along two tracks fixed inside the carbon black storage platform. A manual access door is located on the side of the carbon black storage platform.

[0007] The valve plate has four guide wheels on its edge, and each track is matched with two guide wheels, with the guide wheels pressing on the track.

[0008] A cylinder is installed between the valve plate and the carbon black storage platform. One end of the cylinder's piston end is connected to the valve plate, and the other end is connected to the carbon black storage platform. The valve plate slides between the two tracks by extending and retracting the piston rod of the cylinder.

[0009] The device also includes a scanner, which is electrically connected to a controller, and the controller is electrically connected to a cylinder.

[0010] The technical advantages of this invention are as follows: In addition, this device has a discharge port on the carbon black storage platform, so when unpacking, it no longer relies on cranes and wire ropes, and there will be no safety accidents when the crane slides down or the slings of the ton bag slip off.

[0011] Meanwhile, this device is equipped with a scanner. When the barcode material information does not match the set daily carbon black storage hopper information, the system will be activated to correct the error. Attached Figure Description

[0013] A device for preventing incorrect material feeding by standardized operators includes a carbon black storage platform 6, a feeding port 61 on the carbon black storage platform 6, a valve plate (which is the opening and closing door of the daily storage hopper) 2 below the feeding port 61, the valve plate 2 can slide horizontally along two tracks 3, the tracks 3 are fixed inside the carbon black storage platform 6, and a manual access door 5 is provided on the side of the carbon black storage platform 6.

[0014] To achieve stable sliding, the edge of the valve plate 2 is provided with four guide wheels 4, and each track 3 is matched with two guide wheels 4, with the guide wheels 4 pressing on the track 3.

[0015] To achieve the mechanical drive for sliding, a cylinder 1 is provided between the valve plate 2 and the carbon black storage platform 6. One end of the piston end and the cylinder body end of the cylinder 1 are connected to the valve plate 2, and the other end is connected to the carbon black storage platform 6. The valve plate 2 slides on the two tracks 3 by the extension and retraction of the piston rod of the cylinder 1.

[0016] To prevent errors, the device also includes a scanner 7, which is electrically connected to a controller 8, and the controller 8 is electrically connected to a cylinder 1.

[0017] Its working principle is as follows: S1. System Out of Stock: The daily storage hopper system sends an out of stock signal and starts the feeding operation.

[0018] S2. Lifting to Position: The employee uses a crane to lift the carbon black ton bag to the unloading port 61 of the carbon black ton bag storage platform 1 and checks that the crane wire rope is not under tension.

[0019] S3. Scanning and Identification: The employee scans the material barcode of the carbon black ton bag using the barcode scanner 7. The barcode scanner 7 transmits the information to the controller 8. The controller 8 determines whether the "barcode material information matches the set daily carbon black storage hopper information". If "yes", proceed to step S4; if "no", proceed to step S2 and hoist the new carbon black ton bag. S4. Unpacking operation: The controller 8 sends a signal to the cylinder 1, the cylinder 1 opens the valve plate 2, and the employee enters the carbon black storage platform 6 through the manual access door 5 to carry out the unpacking operation.

[0020] S5. Material unloading operation: Employees exit through manual entrance 5; materials in the carbon black ton bag are fed into the daily storage hopper feeding system.

[0021] S6. Final Operation: After unloading, the crane and carbon black ton bag are moved away. The employee scans the corresponding daily storage hopper barcode with the barcode scanner 7. The barcode scanner 7 transmits the information to the controller 8. The controller 8 sends a signal to the cylinder 1, and the cylinder 8 closes the valve plate 2.

[0022] Features of this application: S1. The device uses a barcode scanner to open and close the door, and records the incoming material information in the MES system for easy traceability. By using the MES system for statistics and counting, manual inventory is eliminated, and the quantity and type of carbon black received during the shift can be directly queried in the MES system. Simultaneously, the MES system performs a count and uploads material information.

[0023] S2. Considering the carbon black dust, a cylinder is used to drive the feeding door, and electrical components such as the solenoid valve are installed in an explosion-proof box, so there is no safety hazard.

[0024] S3. By installing error-proofing devices, automated error prevention is achieved, eliminating the risk of carbon black misplacing and reducing quality accidents. The daily storage hopper is opened and closed by scanning the barcode with a barcode scanner. When the barcode material information matches the set daily storage hopper information, the corresponding daily storage hopper door will open. Only one daily storage hopper door can be opened at a time on a production line. Only one type of carbon black can be fed on the same production line. When scanning the barcodes of other carbon blacks simultaneously, the feeding doors of other daily storage hoppers will not open, thus playing a role in error prevention.

[0025] The S4 carbon black ton bag storage platform can effectively solve the risk of personnel injury caused by falling carbon black ton bags and reduce safety hazards.

[0026] S5. After unloading, the corresponding daily storage hopper barcode needs to be scanned to close the daily storage hopper door, thereby achieving the function of preventing errors.
