Description

Technical Field

[0001] This invention relates to the field of toner cartridge filling equipment technology, and specifically to an automatic toner cartridge filling device. Background Technology

[0002] In the toner cartridge remanufacturing process, the recycled empty toner cartridges need to be refilled with toner. Currently, some small-scale processing still relies on manual labor for toner cartridge handling, alignment, and filling. Manual handling is labor-intensive, and manual alignment is prone to misalignment, resulting in poor filling consistency. Existing filling equipment relies on manual loading and unloading of workpieces, making continuous flow between workstations difficult, leading to insufficient production continuity and limiting batch processing efficiency. During the filling process, toner is a fine powder material, easily generating dust. Conventional equipment lacks effective dust collection structures, and the scattered toner pollutes the work area and adversely affects the health of operators.

[0003] As disclosed in the authorization announcement number CN218675687U, a toner cartridge filling device includes a toner cartridge filling device shell and a second extrusion plate. The bottom of the toner cartridge filling device shell is provided with a discharge shell shell. Multiple sets of connecting rods are evenly arranged on the inner walls of the toner cartridge filling device shell and the discharge shell shell. The other end of the connecting rod is provided with a toner cartridge filling device inner shell. The bottom of the toner cartridge filling device inner shell is provided with a discharge pipe inner shell. Both side walls of the toner cartridge filling device inner shell are provided with movable rods that penetrate the toner cartridge filling device inner shell and extend to the outside of the toner cartridge filling device shell. An extrusion block is provided at the end of the movable rod located inside the toner cartridge filling device inner shell. A sealing ring is provided at the lower part of the outer ring of the toner cartridge filling device shell.

[0004] While it achieves the goal of preventing toner leakage during toner cartridge filling by setting up sealing rings, extrusion blocks, and the outer and inner shells of the toner cartridge filling device, it does not solve the problems that existing toner filling devices are generally not conducive to using cylinder-driven filling actuators for vertical feeding and coordinating with a spiral powder conveying structure for material transport. They also do not facilitate the use of air pressure differences to absorb and collect toner scattered in the work area, cannot effectively suppress dust overflow and diffusion, affecting the working environment, and are inconvenient for workpiece gripping and transfer, thus impacting overall processing efficiency.

[0005] Based on the above, the present invention proposes an automatic toner cartridge filling device. Summary of the Invention

[0035] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0036] Reference Figures 1-9 An automatic toner cartridge filling device includes a frame 1 and a support frame 2. The support frame 2 is provided on the outside of the frame 1. A fixed frame 3 is provided on the outside of the frame 1 on one side of the support frame 2. A belt conveyor 4 is provided on the outside of the frame 1 on one side of the fixed frame 3.

[0037] A first servo motor 6 is installed on the outer wall of the frame 1. A synchronous pulley assembly 7 is provided at the output end of the first servo motor 6. A drive shaft 8 is movably installed on the top of the frame 1 on one side of the synchronous pulley assembly 7. The synchronous pulley assembly 7 extends to the surface of the drive shaft 8. Drive sprockets 9 are symmetrically fitted on the surface of the drive shaft 8. Chains 11 are fitted on the surface of each drive sprocket 9.

[0038] A driven shaft 14 is movably mounted on the top of the frame 1 on the side away from the drive shaft 8. Driven sprockets 15 are symmetrically mounted on the surface of the driven shaft 14, and the chains 11 all extend to the surface of the driven sprockets 15 on the adjacent side.

[0039] Multiple sets of fixing seats 10 with equal spacing are provided between the two sides of the chain 11. A connecting block 18 is installed on the outer wall of the chain 11 on one side of the fixing seat 10, and the fixing seat 10 is connected to the connecting block 18 on the adjacent side.

[0040] The top of the frame 1 on one side of the chain 11 is equipped with an upper limit track 12, and the inside of the frame 1 below the upper limit track 12 is equipped with a lower limit track 13. Limit wheels 19 are movably installed on the outer walls of both sides of the fixed seat 10, and the limit wheels 19 are slidably connected to the upper limit track 12 and the lower limit track 13.

[0041] A lifting cylinder 21 is installed at the top of the support frame 2. An adjusting frame 20 is installed at the output end of the lifting cylinder 21. Guide rods 22 are symmetrically installed at the bottom end of the adjusting frame 20. The guide rods 22 extend to the outside of the support frame 2. Guide sleeves 23 are slidably fitted on the surface of the guide rods 22 near the support frame 2. The guide sleeves 23 are connected to the support frame 2.

[0042] A second servo motor 24 is installed at the top of the adjusting frame 20. A hopper 25 is installed at the bottom of the adjusting frame 20 below the second servo motor 24. A goose shank tube 28 is installed on the outer wall of the hopper 25. A solenoid valve 26 is installed at the bottom of the hopper 25. A conical feeding nozzle 27 is installed at the bottom of the solenoid valve 26.

[0043] The hopper 25 is equipped with a spiral blade 29, and the output end of the second servo motor 24 is connected to the spiral blade 29. A discharge photoelectric sensor 16 is installed on the top of the frame 1 on the side of the driven shaft 14, and a powder filling photoelectric sensor 17 is installed on the top of the frame 1 on the side of the discharge photoelectric sensor 16.

[0044] The manual placement of the toner cartridge to be filled onto the surface of the fixed base 10 is achieved by the PLC controller 5 controlling the opening of the first servo motor 6. Supported by the frame 1, the first servo motor 6 drives the synchronous pulley assembly 7 to move, which in turn drives the drive shaft 8 to rotate. With the movable support of the frame 1 on the drive shaft 8, the drive shaft 8 drives two sets of drive sprockets 9 to rotate, which in turn drives the chain 11 to move. With the movable support of the frame 1 on the driven shaft 14, and with the support of the driven shaft 14 on the driven sprocket 15, the driven sprocket 15 provides movable support for the chain 11. The chain 11 drives the fixed base 10 to move via the connecting block 18. The limiting wheel 19 slides on the surfaces of the upper limit track 12 and the lower limit track 13 to provide sliding support for the fixed base 10, facilitating the forward movement of the toner cartridge on the drive surface of the fixed base 10.

[0045] When the toner cartridge photoelectric sensor 17 detects the toner cartridge, it feeds back the signal to the PLC controller 5 so that the PLC controller 5 can control the first servo motor 6 to stop rotating, so that the toner cartridge can move to the bottom of the conical feeding nozzle 27. At the same time, the PLC controller 5 controls the lifting cylinder 21 to open. With the support of the support frame 2, the lifting cylinder 21 drives the adjusting frame 20 to move downward. The guide rod 22 slides inside the guide sleeve 23 to provide sliding support for the adjusting frame 20. The adjusting frame 20 drives the hopper 25, the solenoid valve 26, and the conical feeding nozzle 27 to move downward, so that the conical feeding nozzle 27 can be inserted into the inside of the toner cartridge.

[0046] The PLC controller 5 controls the second servo motor 24 and the solenoid valve 26 to open. With the support of the adjusting frame 20, the second servo motor 24 drives the spiral blade 29 to rotate. With the hopper 25 supporting the spiral blade 29, the spiral blade 29 can easily fill the toner inside the hopper 25 through the solenoid valve 26 and the conical feeding nozzle 27 into the drum. At the same time, the gooseneck tube 28 is manually connected to the negative pressure suction source of an external industrial vacuum cleaner. The external vacuum cleaner creates a negative pressure inside the gooseneck tube 28, and the excess toner scattered in the air during filling is sucked out by the air pressure difference, reducing the toner from escaping.

[0047] The gooseneck tube 28 is a bent, sealed metal flexible tube. After filling is completed, the PLC controller 5 controls the second servo motor 24 and the solenoid valve 26 to close, and the PLC controller 5 controls the lifting cylinder 21 to open in the reverse direction to facilitate the upward movement of the hopper 25, the solenoid valve 26, and the conical feeding nozzle 27 for resetting. At the same time, the PLC controller 5 controls the first servo motor 6 to open again to facilitate the continued forward movement of the filled toner cartridge.

[0048] A transverse moving frame 30 is slidably mounted on the top of the fixed frame 3. A longitudinal moving arm 35 is slidably mounted on the outer wall of the transverse moving frame 30.

The output end of the longitudinal servo motor 32 is connected to the longitudinal gear 33.

[0049] Longitudinal slide rails 41 are symmetrically installed on the outer wall of the longitudinal moving arm 35 near the transverse moving frame 30. Longitudinal sliders 42 are slidably installed on the outer wall of each longitudinal slide rail 41, and the longitudinal sliders 42 are connected to the transverse moving frame 30.

[0050] A horizontal servo motor 36 is mounted on the top of the horizontal moving frame 30. A horizontal gear 37 is provided on the outside of the horizontal moving frame 30 below the horizontal servo motor 36, and the output end of the horizontal servo motor 36 is connected to the horizontal gear 37. A horizontal rack 38 is mounted on the top of the fixed frame 3 on one side of the horizontal gear 37, and the horizontal gear 37 meshes with the horizontal rack 38. A horizontal slide rail 39 is symmetrically mounted on the top of the fixed frame 3 on one side of the horizontal rack 38. A horizontal slider 40 is symmetrically slidably mounted on the top of each horizontal slide rail 39, and the horizontal slider 40 is connected to the horizontal moving frame 30.

[0051] A PLC controller 5 is installed on the side of the frame 1 away from the belt conveyor 4. The output terminal of the PLC controller 5 is electrically connected to the input terminals of the belt conveyor 4, the first servo motor 6, the discharge photoelectric sensor 16, the powder filling photoelectric sensor 17, the lifting cylinder 21, the second servo motor 24, the solenoid valve 26, the longitudinal servo motor 32, the pneumatic gripper 34, and the transverse servo motor 36.

[0052] When the discharge photoelectric sensor 16 detects that the toner cartridge has been filled, the discharge photoelectric sensor 16 feeds back the signal to the PLC controller 5 so that the PLC controller 5 can control the first servo motor 6 to stop again. At the same time, the PLC controller 5 controls the horizontal servo motor 36 to open. With the support of the horizontal moving frame 30, the horizontal servo motor 36 drives the horizontal gear 37 to rotate. With the meshing of the horizontal gear 37 and the horizontal rack 38, the horizontal gear 37 drives the horizontal moving frame 30 to move. The horizontal slider 40 slides on the surface of the horizontal slide rail 39 to provide sliding support for the horizontal moving frame 30. The horizontal moving frame 30 drives the vertical moving arm 35 and the pneumatic gripper 34 to move above the toner cartridge.

[0053] The PLC controller 5 controls the longitudinal servo motor 32 to open. Supported by the transverse moving frame 30, the longitudinal servo motor 32 drives the longitudinal gear 33 to rotate. Under the meshing of the longitudinal gear 33 and the longitudinal rack 31, the longitudinal gear 33 drives the longitudinal rack 31 to move. The longitudinal rack 31 drives the longitudinal moving arm 35 to move. The longitudinal slide rail 41 slides inside the longitudinal slider 42 to provide sliding support for the longitudinal moving arm 35, so as to facilitate the longitudinal moving arm 35 to drive the pneumatic gripper 34 to move to the side of the toner cartridge.

[0054] The PLC controller 5 controls the pneumatic gripper 34 to open, so as to facilitate the clamping of the toner cartridge. The PLC controller 5 controls the longitudinal servo motor 32, the transverse servo motor 36, and the pneumatic gripper 34 to open in reverse, so as to facilitate the placement of the filled toner cartridge on the surface of the belt conveyor 4. The PLC controller 5 controls the belt conveyor 4 to open, so as to facilitate the movement of the filled toner cartridge to the next process.

[0055] In this embodiment of the application, in order to achieve the coordinated operation of the above-mentioned functional modules, the PLC controller 5 can be a commercially available conventional product control device, such as the SIMATIC S7-1500. The PLC controller 5 is electrically connected to each electrical component through wires. According to the signals fed back by various sensors, the PLC controller 5 drives the corresponding actuator to act according to preset logic such as threshold comparison and timing control. The hydraulic source / air source / power supply, pipelines / wires and control valves / switches required for its drive are all commercially available conventional products. The specific implementation of the above control circuit is a conventional technical means in this field and will not be described in detail here.

[0056] Working principle of the invention:

[0057] First, the drum to be filled with toner is manually placed on the surface of the fixed base 10. The first servo motor 6 drives the synchronous belt pulley assembly 7 to move, which in turn drives the drive shaft 8 to rotate. The drive shaft 8 drives two sets of drive sprockets 9 to rotate, which in turn drives the chain 11 to move. The driven sprocket 15 provides movable support for the chain 11. The chain 11 moves the fixed base 10 via the connecting block 18, and the fixed base 10 drives the drum on its surface to move forward. When the toner filling photoelectric sensor 17 detects the drum, it feeds a signal back to the PLC controller 5, allowing the PLC controller 5 to stop the first servo motor 6, thus facilitating the movement of the drum below the conical feeding nozzle 27 and its lifting. Cylinder 21 drives adjusting frame 20 to move downwards, which in turn drives hopper 25, solenoid valve 26, and conical feeding nozzle 27 to move downwards, facilitating the insertion of conical feeding nozzle 27 into the drum. Second servo motor 24 drives spiral blade 29 to rotate, facilitating the filling of toner from hopper 25 into the drum via solenoid valve 26 and conical feeding nozzle 27. PLC controller 5 controls second servo motor 24 and solenoid valve 26 to close, and controls lifting cylinder 21 to open in the reverse direction, facilitating the upward movement of hopper 25, solenoid valve 26, and conical feeding nozzle 27 for resetting, thus facilitating the continued forward movement of the filled drum to complete the operation of the filling device.
