Description

Technical Field

[0001] This utility model relates to the technical field of automatic toner cartridge production equipment, and in particular to a tray stacking device for waste toner hoppers. Background Technology

[0002] A toner cartridge, also known as a photosensitive drum, is generally composed of a base material made of aluminum and a photosensitive material coated on the base material. The waste toner container of the toner cartridge is a component in laser printers used to collect waste toner generated during use. Previously, it was necessary to manually move the trays over, place the waste toner containers into the trays, and then stack the trays containing the waste toner containers. This was labor-intensive, time-consuming, and inefficient. Utility Model Content

[0003] The purpose of this invention is to overcome the shortcomings of the existing technology and to provide a tray stacking device for waste powder silos.

[0004] The objective of this invention is achieved through the following technical solution: A waste powder silo palletizing device includes a silo tilting and transport mechanism, a palletizing robot, a pallet conveying mechanism, a pallet lifting mechanism, a pallet stacking mechanism, a frame, and a controller. The silo tilting and transport mechanism, the palletizing robot, the pallet conveying mechanism, the pallet lifting mechanism, and the pallet stacking mechanism are all mounted on the frame. The lower end of the pallet conveying mechanism is connected to the pallet lifting mechanism, and the middle part of the pallet stacking mechanism is connected to the pallet lifting mechanism. The upper end of the pallet lifting mechanism is connected to the silo tilting and transport mechanism via the palletizing robot. All four components—the silo tilting and transport mechanism, the palletizing robot, the pallet conveying mechanism, the pallet lifting mechanism, and the pallet stacking mechanism—are connected to the controller. This device enables automatic palletizing and stacking of waste powder silos, improving production efficiency and reducing labor costs and labor intensity.

The outer side of the first Z-axis moving structure 24 is connected to the second Z-axis moving structure 24 via two Z-axis fixing plates 26. The moving end of each Z-axis moving structure 24 is connected to one of the two powder hopper clamping structures 25. The X-axis moving structure 22, Y-axis moving structure 23, Z-axis moving structure 24, and the two powder hopper clamping structures 25 are all connected to a controller 7.

The insert plate lifting fixing seat 5311 is installed on the outside of the encoder guide bracket 51. The insert plate lifting cylinder 5315 is fixedly installed on the outside of the insert plate lifting fixing seat 5311, and the cylinder of the insert plate lifting cylinder 5315 is connected to the middle of the insert plate lifting base 5314. The left and right ends of the insert plate lifting base 5314 are respectively connected to the two insert plate lifting sliders 5313.

Two insert plate lifting slide rails 5312 are mounted on the insert plate lifting fixing base 5311, located on both sides of the insert plate lifting cylinder 5315. The left and right ends of the insert plate 5318 are fixedly connected to two insert plate transverse sliding blocks 5317. The two insert plate transverse sliding blocks 5317 are slidably connected to two insert plate transverse slide rails 5316.

Both the insert plate lifting cylinder 5315 and the insert plate transverse cylinder 5319 are controlled by the controller 7.

[0047] The tray lifting and fixing base 5311 serves as a support. The cooperation of the tray lifting slide rail 5312 and the tray lifting slider 5313 guides the tray lifting base 5314. The tray lifting base 5314 is used to fix and install two tray transverse slide rails 5316. The tray lifting cylinder 5315 provides power for the lifting and lowering of the tray lifting base 5314. The cooperation of the tray transverse slide rails 5316 and the tray transverse slider 5317 guides the tray 5318. The tray 5318 is used to support the tray containing the waste powder bin. The tray transverse cylinder 5319 provides power for the inward and outward movement of the tray 5318.

[0048] Workers place multiple stacked empty pallets into the pallet limiting bracket 31 of the pallet conveying mechanism 3. The pallet lifting machine 32 supports the stacked empty pallets. When an empty pallet is needed, the pallet lifting machine 32 descends, and the bottom empty pallet falls onto the pallet conveyor line 33. Driven by the pallet conveyor line 33 and limited by the pallet limiting bracket 31, the bottom empty pallet separates from the empty pallets above it and is transferred to the pallet loading / unloading structure 42 of the pallet lifting mechanism 4. The pallet lifting structure 41 moves the empty pallet upward to the top of the pallet lifting structure 41. At this time, the empty pallet moves into the pallet loading robot 2 and is positioned. The previous process equipment or personnel place the waste powder bins onto the powder bin conveyor line 11. The powder bin conveyor line 11 moves the waste powder bins from its right end to its left end. The powder bin flipping structure 12 grabs the waste powder bins at the left end, and the waste powder bins are flipped 180 degrees around the flipping shaft 123. The powder bin clamping structure 25 of the pallet loading robot 2 picks up the waste powder bins flipped by the powder bin flipping structure 12 and places them sequentially into empty pallets. After the pallet is full of waste powder bins, the pallet lifting structure 41 of the pallet lifting mechanism 4 moves the pallet containing the waste powder bins downward. When it moves to the middle position of the pallet lifting structure 41, that is, when the pallet lifting structure 41 connects with the pallet feeding conveyor belt 52 of the pallet stacking mechanism 5, the pallet containing the waste powder bins moves into the pallet stacking structure 53 under the action of the pallet loading / unloading structure 42 and the pallet feeding conveyor belt 52. The pallet lifting assembly 532 of the pallet stacking structure 53 lifts the pallet containing the waste powder bin. The insert lifting assembly 531 inserts into both sides of the pallet, raising it to a certain height. The pallet lifting assembly 532 then retracts below the pallet feeding conveyor belt 52. A subsequent pallet enters the pallet stacking structure 53 and is positioned directly below the lifted pallet. The pallet lifting assembly 532 lifts it again, completing the stacking of the two pallets. Under the lifting of the pallet lifting assembly 532, the insert plates 5318 of the insert lifting assembly 531 retract and descend, reaching the sides of the bottom pallet. This process is repeated to stack the pallets containing the waste powder bin. Once the pallets are stacked to a certain height, they are removed by workers.
