Description

Technical Field

[0001] This invention relates to a novel all-roller pallet conveying device, which is particularly suitable for raw material conveying sites in the new energy industry and belongs to the field of logistics and warehousing. Background Technology

[0002] In the logistics and warehousing industry, various pallet conveying equipment is commonly used. However, existing equipment is insufficient to meet the demands of the rapidly developing new energy and new material production sector. For example, during the conveying of lithium iron phosphate and ternary lithium batteries, it is required that the pallets and conveying equipment be free of powder or debris to prevent contamination of these materials during transport and storage, which could significantly reduce their activity and performance.

[0003] In existing pallet conveying systems, one type typically uses chain conveyors, where chain wear debris or grease adheres to the pallets, easily contaminating the goods being transported. Another type typically uses traditional equipment such as roller conveyors with roller turntables, which also struggle to avoid contamination and have low operational efficiency. Furthermore, the turntable conveying speed, while ensuring stable stacking of goods, is difficult to increase to meet the requirements for conveying materials in the aforementioned special industries. Moreover, the roller conveyors are prone to significant pallet wear and jamming.

[0004] In view of the above, this patent application is hereby filed. Summary of the Invention

[0039] Example 1, as Figures 1 to 9-2 As shown, a novel all-roller conveyor system is applied to the automated warehousing operation site of the new energy material production industry. The system includes a single-row roller conveyor 7 forming a conveyor loop. A double-row small roller rotary table 1, a single-row roller transfer machine 2 and a double-row small roller conveyor 3 are connected to the inbound end of the single-row roller conveyor 7. A pallet double-row small roller conveyor 9 is connected to the outbound end of the single-row roller conveyor 7. An air shower 5 and a transition room 10 are fixedly installed on the conveyor line of the single-row roller conveyor 7.

[0040] To improve the passage efficiency of goods through the air shower 5 and / or transition room 10 during the conveying process of goods along the single-row roller conveyor 7, and to improve the isolation effect of the internal and external environment during the air shower cleaning process, it is preferable to set up a double-row small roller moving trolley 4 inside the air shower 5 and / or transition room 10 for connecting and conveying goods.

[0041] To achieve automated control of the cyclical transport of pallets in and out of the warehouse, a pallet unpacking machine 6 and a stacker crane 8 can be connected and installed between the transport loop and the storage rack.

[0042] Based on the overall structural design of the above-mentioned all-roller conveyor system, the following inbound and outbound processes can be realized by applying this application:

[0043] Inbound Process: 1) A pallet is separated from the pallet stack using a pallet unpacking machine 6; 2) The pallet is conveyed from the pallet unpacking machine 6 sequentially through a double-row small roller conveyor 3 and a single-row roller transfer machine 2 to the conveyor line of a single-row roller conveyor 7, and then transferred to the double-row small roller rotary table 1 at the inbound end to await goods inbound; 3) Operators use forklifts to place the goods on the pallet on the double-row small roller rotary table 1; 4) The pallet and goods are rotated on the double-row small roller rotary table 1 and connected to the double-row small roller conveyor 3 again, and transferred to the conveyor line of the single-row roller conveyor 7 via the single-row roller transfer machine 2; 5) The pallet and goods are carried by a double-row small roller moving trolley 4 into the air shower room 5 for dust removal by spraying; 6) After dust removal, the pallet and goods are transferred by the double-row small roller moving trolley 4 to the double-row small roller conveyor 3 and then to the stacker crane 8, and finally the goods are stored in the warehouse on the shelves.

[0044] Outbound: 1) Goods are taken out of the stacker crane 8 and transported to the double-row small roller conveyor 3; 2) They are transferred to the single-row roller transfer machine 7 via the single-row roller transfer machine 2 for continued transport; 3) They are sent into the transition room 10 via the double-row small roller moving trolley 4; 4) They are transferred to the double-row small roller conveyor 3 via the single-row roller conveyor 7, and finally arrive at the pallet jack double-row small roller conveyor 9, where they wait for the operators to use the pallet jack forklift to pick up the goods.

[0045] The double-row small roller rotary table 1 includes a rotary table frame 15, a rotary power assembly 11 is provided on the rotary table frame 15, the rotary power assembly 11 is driven and connected to the rotary frame assembly 12, and a small roller conveying assembly 14 is provided on the rotary frame assembly 12 and driven and connected by the conveying power assembly 13.

[0046] The rotary power assembly 11 includes a rotary support 114 axially mounted on the rotary table frame 15 and a rotary drive motor 112. The output end of the rotary drive motor 112 is fitted with a drive gear 113, which meshes with the outer peripheral gear of the rotary support 114. The rotary support 114 is vertically connected to the rotary frame assembly 12.

[0047] Driven by the rotary drive motor 112, the slewing support 114 drives the rotating frame assembly 12 to rotate, thereby carrying pallets and goods to connect with conveyor lines in different directions within a 360° range, such as connecting with the double-row small roller conveyor 3 for conveying.

[0048] The conveying power assembly 13 includes an intermediate sprocket 135, a tension sprocket 136 and a rotary table conveying motor 132, which are mounted on both sides of the rotating frame assembly 12. The output end of the rotary table conveying motor 132 is fitted with a motor sprocket 133. A chain assembly 134 is connected in a closed loop between the intermediate sprocket 135, the tension sprocket 136 and the motor sprocket 133. Two sets of intermediate sprockets 135 are fitted on the drive rollers 141 of the small roller conveying assembly 14 from both sides.

[0049] Driven by the rotary table conveyor motor 132, and transmitted by the chain assembly 134 and the intermediate sprocket 135, the drive roller 141 of the small roller conveyor assembly 14 rotates axially. Through the transmission components such as the synchronous belt 142, the other driven rollers 143 in the small roller conveyor assembly 14 can jointly provide a forward conveying driving force to the pallet and goods.

[0050] The single-row roller transfer machine 2 includes a transfer machine base frame assembly 21, a lifting frame assembly 22 that is vertically slidably connected to the transfer machine base frame assembly 21, and a roller conveyor assembly 23 that is connected to the lifting frame assembly 22 and driven by the transfer machine conveyor drive assembly 24.

[0051] Two sets of lifting shafts 217 and lifting motors 212 are symmetrically mounted on the transfer machine base frame assembly 21 via bearings 218 at the shaft ends. Lifting driven sprockets 215 are mounted on the lifting shafts 217 via expansion sleeves 216 and lifting eccentric blocks 219 are mounted on the lifting shafts 217 via needle roller bearings 2110. Lifting motor sprockets 213 are mounted on the output end of the lifting motors 212. Lifting chains 214 are connected in a closed loop between the lifting motor sprockets 213 and the lifting driven sprockets 215.

[0052] The bottom of the lifting frame assembly 22 is in close contact with the lifting eccentric block 219, and the lifting frame assembly 22 is fitted onto the guide optical shaft 2111, which is vertically fixed to the transfer machine base frame assembly 21 through the guide sleeve 2112.

[0053] Driven by the lifting motor 212, the lifting chain 214 runs to drive the lifting shaft 217 to rotate. While the lifting shaft 217 rotates, the lifting eccentric block 219 drives the lifting frame assembly 22 to lift and lower, thereby changing the working height of the pallet and goods carried on the roller conveyor assembly 23, and realizing the connection and conveying between conveyor assemblies at different heights, such as the single-row roller conveyor 7.

[0054] The transfer machine conveyor drive assembly 24 can adopt the same transmission structure and operating principle as the conveyor power assembly 13.

[0055] The double-row small roller conveyor 3 includes a double-row small roller frame 32 mounted on the ground via a support leg assembly 33, and a double-row roller assembly 34 mounted on the double-row small roller frame 32 and driven by a roller drive assembly 31.

[0056] Among them, the double-row roller assemblies 34 have a horizontal gap of more than 150mm to allow pallet legs with a width of about 150mm to pass between the double-row roller assemblies 34, and the goods carried by the pallet can be smoothly transported forward on the double-row roller assemblies 34.

[0057] To withstand heavy loads of 1.2 tons or more, the roller drive assembly 31 of this application can adopt the same transmission structure and operating principle as the conveying power assembly 13. Meanwhile, the double-row roller assembly 34 has double-row active rollers 35 driven by sprockets and chains and double-row passive rollers 36 without sprockets and chains arranged at intervals. All rollers are covered with a wear-resistant rubber layer to increase the friction between the conveying pallet and the goods and prevent the pallet from getting stuck during the conveying process.

[0058] Furthermore, the shaft end mounting position of the unpowered double-row driven roller 36 is 1mm lower in the vertical direction than the shaft end mounting position of the powered double-row driven roller 35, thereby preventing pallets and goods from having difficulty overcoming the higher double-row driven roller 35 when being transported to the driven roller 35 due to the lack of power; conversely, pallets and goods can be pushed down by the driving force of the double-row driven roller 35 to reach the unpowered double-row driven roller 36, and finally transported to the next station under the drive of the roller drive assembly 31.

[0059] The double-row small roller mobile trolley 4 includes a mobile power assembly 41 mounted on the bottom frame 45, an upper mobile assembly 42 driven by the mobile power assembly 41, and a small roller conveying assembly 44 set on the upper mobile assembly 42 and driven by the conveying power assembly 43.

[0060] The mobile power assembly 41 includes a mobile power motor 411, the output end of which is fitted with a mobile motor sprocket 412. The mobile motor sprocket 412 and the mobile driven sprocket 415 installed on one side of the bottom frame 45 are connected in a closed loop by a mobile chain 413. The mobile chain 413 is fixedly connected to the upper mobile assembly 42 by a fixing block 416. The bottom of the upper mobile assembly 42 is slidably embedded in the bottom slide rail 417 on the bottom frame 45 by a connected bottom guide rail slider 414.

[0061] Driven by the mobile power motor 411, the upper moving component 42 moves horizontally via the mobile chain 413, so that the small roller conveying component 44 connects to the conveying pallet and goods and guides them into or pushes them out of the air shower room 5 and the transition room 10.

[0062] The power transmission component 43 can adopt the same transmission structure and operating principle as the power transmission component 13.

[0063] The air shower room 5 is designed for special production fields such as new energy and new materials to meet the high standards and high quality requirements of the cleanliness of the carriers in such conveying sites. That is, the goods that enter the shelf storage must be blown by the air shower before they can be put into the warehouse, and air isolation is required inside and outside the warehouse.

[0064] Specifically, the air shower 5 is located on the conveyor line between the single-row roller machine 7 and the double-row small roller moving trolley 4. It has a first door 51 and a second door 52 that open and close at different times. A blower 53 is installed inside the air shower 5.

[0065] After the double-row small roller moving trolley 4 connects to the pallet and goods conveyed from the single-row roller machine 7, the first door 51 is opened and the second door 52 is kept closed. Then, the moving power component 41 drives the upper moving component 42 to carry the pallet and goods into the air shower chamber 5. After the first door 51 is closed, the air shower cleaning is carried out. After the air shower operation is completed, the first door 51 is kept closed and the second door 52 is opened. The upper moving component 42 sends the pallet and goods out of the air shower chamber 5 and connects to the single-row roller machine 7 to continue forward conveying. Then the second door 52 is closed.

[0066] The decoy plate machine 6 includes a decoy plate frame assembly 61, and two sets of decoy plate lifting assemblies 63 are symmetrically arranged on both sides inside the decoy plate frame assembly 61 and driven by the lifting drive assembly 62. The extension fork assembly 64 is connected to the decoy plate lifting assembly 63.

[0067] The lifting drive assembly 62 includes a lifting drive shaft 628, a decode disc motor 621, and an axially fixed lifting auxiliary sprocket 627, which are connected transversely to both sides of the inside of the decode disc frame assembly 61 via bearings with bearing seats at the shaft ends. A lifting motor sprocket 622 is sleeved on the output end of the decode disc motor 621. An intermediate sprocket 624 and a lifting sprocket 625 are sleeved on the lifting drive shaft 628. A lifting drive chain 623 is connected in a closed loop between the lifting motor sprocket 622 and the intermediate sprocket 624. A lifting chain 626 is wound in a closed loop between the lifting sprocket 625 and the lifting auxiliary sprocket 627 in the vertical direction. The lifting chain 626 passes through and is fixedly connected to the decode disc lifting assembly 63.

[0068] The pallet unpacking lifting assembly 63 includes a lifting frame 631, a lifting chain 626 fixedly connected to the lifting frame 631, and the side of the lifting frame 631 is slidably engaged with the lifting frame guide rail 632 fixedly installed on the pallet unpacking frame assembly 61 via a slider; driven by the lifting chain 626, the lifting frame 631 moves vertically up and down on the lifting frame guide rail 632 to pick up or release the pallet through the fork extension assembly 64, thereby changing the working height of the pallet and performing unpacking or stacking operations.

[0069] The fork extension assembly 64 includes a rod motor 641 mounted on the lifting frame 631. The output end of the rod motor 641 is fixedly connected to a movable bracket 642. Fork plates 644 are provided at both ends of the movable bracket 642. The bottom of the movable bracket 642 is slidably connected to a slider guide rail 643 fixedly mounted on the lifting frame 631 via a slider.

[0070] The pallet unpacking and unpacking machine 6 described above can be used to perform palletizing and unpacking operations according to operational needs. Specifically, the palletizing process includes: an empty pallet enters the pallet unpacking and unpacking machine 6, and the lifting drive component 62 lowers the pallet unpacking lifting component 63 to a low position; then, the fork extension component 64 extends the fork plate 644 into the fork hole of the pallet, and the lifting drive component 62 drives the pallet unpacking lifting component 63 to lift the pallet to a high position; then, the next empty pallet enters the pallet unpacking and unpacking machine 6, and the lifting drive component 62 drives the pallet unpacking lifting component 63 to lower the pallet to the top of the pallet that just entered, and the fork plate 644 retracts to complete one palletizing process. This cycle is repeated to complete the empty pallet stacking operation for all pallet types and quantities required.

[0071] The depalletizing process includes: if a pallet stack consisting of 10 empty pallets enters the depalletizing machine 6, the lifting drive assembly 62 lowers the depalletizing lifting assembly 63 to the fork plate 644 so that it aligns with the fork hole position of the second pallet counting from the bottom in the pallet stack. The fork plate 644 extends so that the second pallet and all pallets above it are lifted to the high position. Then, the original bottom empty pallet is conveyed out of the depalletizing machine 6. Subsequently, the lifting drive assembly 62 lowers the depalletizing lifting assembly 63 along with the pallet stack to the low position, and the fork plate 644 retracts to complete one depalletizing process. This cycle is repeated until all pallets are depalletized one by one and conveyed out of the depalletizing machine 6.

[0072] The single-row roller conveyor 7 is used to transport pallets and goods in the horizontal direction. It can adopt the common roller conveyor line structure and operating principle of existing technology, which will not be described in detail here.

[0073] The stacker crane 8 is used to transfer goods on pallets from the single-row roller conveyor 7 to designated storage positions in the racking system, or to transfer goods out of the warehouse back to the single-row roller conveyor 7 and then to the aforementioned double-row small roller conveyor 9 for outbound delivery. The stacker crane 8 can adopt the existing technology of a loading platform structure and operating principle that operates vertically between the overhead rail and the ground rail, which will not be described in detail here.

[0074] The aforementioned double-row pallet jack conveyor 9 is used to carry pallets and goods, so that operators can use pallet jack forklifts to pick up and transport the goods. The double-row pallet jack conveyor 9 can adopt the same structural design and operating principle as the double-row pallet conveyor 3, except that a pallet jack platform 92 for pallet jack forklifts to travel on and pick up goods is fixedly connected to the double-row pallet jack frame 91.

[0075] The transition room 10 does not have a built-in hair dryer 53, but its other structural design and operating principle are the same as those of the air shower room 5, and will not be described in detail here.

[0076] As described above, the embodiments given in conjunction with the accompanying drawings are merely preferred solutions for achieving the objectives of this invention. Those skilled in the art can draw inspiration from this and directly derive other alternative structures that conform to the design concept of this invention. Other structural features derived therefrom should also fall within the scope of the solutions described in this invention.
