Description

Technical Field

[0001] This invention relates to the field of conveyor technology, specifically to a type I chain conveyor. Background Technology

[0002] With the decreasing supply of urban land resources nationwide and the tight supply of land resources in large cities, large-scale automated storage and retrieval systems (AS / RS) technology has been developing rapidly in the logistics industry.

[0003] The original automated warehouse outbound operations consisted of outbound operations for entire palletized goods and outbound operations for single or multiple items from a palletized goods. In the outbound operations for single or multiple items from a palletized goods, floor platforms were used in conjunction with platform trolleys to transport the pallets back and forth.

[0004] When a customer needs one or more items from a pallet of goods in the automated storage and retrieval system (AS / RS), the AS / RS stacker crane forks the pallet from the rack and places it on the outbound trolley. The trolley then transports the pallet along the track to the picking position at the outbound platform. The operator retrieves the required quantity of goods and clicks the "picking complete" confirmation button. The trolley then transports any unpicked pallets to the stacker crane's pickup location, and the stacker crane returns the picked pallets to their original storage location within the AS / RS.

[0005] When a customer needs a full pallet of goods in the automated warehouse, the stacker crane directly forks the pallet from the warehouse rack and places it on the outbound trolley. The trolley then transports the pallet along the track to the picking position at the outbound platform, where operators use a manual hydraulic trolley to pull the entire pallet away.

[0006] For the picking operations of palletized goods in the automated storage and retrieval system (AS / RS) that require returning to the warehouse, when the goods on the pallet are picked multiple times, the pallet will repeatedly travel back and forth between the AS / RS racks and the platform trolleys. When the number of back-and-forth trips is too high, the lack of positioning and correction devices on the platform trolleys and the stacker crane's handling error can cause the pallet position to shift. When the shift reaches a certain critical value, the stacker crane will trigger a protection alarm. After the alarm is triggered, the stacker crane must be manually operated to move the goods to the ground floor chain conveyor for manual correction, which greatly affects the stacker crane's efficiency. At the same time, if the pallet offset is too large, there is also a risk of the pallet tipping over and the goods falling off.

[0007] Based on this, the present invention addresses the problem of pallet storage position displacement in existing pharmaceutical logistics center automated warehouses by designing an I-type chain plate conveyor. Summary of the Invention

[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] This invention provides a type I chain conveyor, including a chain conveyor for conveying goods. Both ends of the chain conveyor are provided with brackets 5. A detection photoelectric switch is provided in the middle of the bottom end of the bracket 5. The detection photoelectric switch is used to detect whether there is a pallet on the chain conveyor. The detection photoelectric switch is prior art and can be a lens-type photoelectric switch. The photoelectric body 8 of the lens-type photoelectric switch is set on one bracket 5, and the reflective lens 9 of the lens-type photoelectric switch is set on another bracket 5.

[0034] The bottom of the bracket 5 is equipped with a limit switch 7. The limit switch 7 can limit the pallet to prevent the pallet from going out of the chain machine limit and breaking the chain and chain plate.

[0035] The chain conveyor includes a support frame 1. Stop and correction blocks 6 are provided at the head, tail, and sides of the chain conveyor. The stop and correction blocks 6 on the sides of the support frame 1 can adjust the position of the pallet. The stop and correction blocks 6 at the head and tail of the chain conveyor can limit and correct the position of the pallet, preventing it from moving. Furthermore, the stop and correction blocks 6 at the head and tail of the chain conveyor can be mounted on the support frame 1 or on the bracket 5.

[0036] Both ends of the support frame 1 are equipped with proximity switches 3. The proximity switches 3 can detect the position of the pallet and determine whether the pallet has reached the fixed position. One side of one end of the support frame 1 is equipped with a pallet limiting block 14. The pallet limiting block 14 can position the pallet, making it easy to place the loaded pallet on the chain conveyor.

[0037] The top of the support frame 1 is provided with a placement slot, and a chain 2 is movably connected in the placement slot. There are three placement slots in this application, and each placement slot is provided with a chain 2. The three chains 2 are in a horizontal state relative to each other. The support frame 1 can be made of carbon steel.

[0038] Both ends of the inner cavity of the placement slot are movably connected to driven wheels, and a driving wheel 27 is located below the placement slot. The driven wheels and driving wheels 27 are connected by a chain 2. Two adjacent driving wheels 27 are fixedly connected by a connecting rod, which is movably connected to the support frame 1. A servo motor 31 is located at the bottom of the support frame 1, and the connecting rod is driven by the servo motor 31. When the servo motor 31 is working, it can drive the connecting rod to rotate, which in turn drives the driving wheel 27 to rotate, and the driving wheel 27 drives the chain 2 to rotate.

[0039] Two chain plates 4 are fixedly connected to the top of the chain 2. The chain plates 4 are rectangular in structure and can be connected to the chain 2 using chain buckles. The chain plates 4 are used for a manual hydraulic trolley to drive onto the chain machine to move the pallet.

[0040] The inner cavity of the placement slot is equipped with a lubrication structure, which includes two application wheels 21 movably connected to the inner cavity of the placement slot, an oil spray plate 20 disposed between the two application wheels 21, and a sound sensor 19 connected to the oil spray plate 20. The application wheels 21 are in contact with the bottom of the upper straight section and the top of the lower straight section of the chain 2, and the bottom of the oil spray plate 20 is evenly provided with lubricating oil spray holes. An oil inlet pipe 17 is fixedly connected to one side of the inner cavity of the oil spray plate 20, and the other end of the oil inlet pipe 17 extends to the bottom of the support frame 1. With the setting of the lubrication structure, when the lubricating oil for lubricating the chain 2 is injected into the oil spray plate 20 through the oil inlet pipe 17, the lubricating oil can be sprayed onto the chain 2 through the lubricating oil spray holes. When the chain 2 rotates, the application wheels 21 can spread the lubricating oil sprayed on the chain 2 evenly, and the upper straight section and the lower straight section of the chain 2 can be lubricated at the same time to avoid the occurrence of lubrication dead zones.

[0041] A tension adjustment structure is provided below the placement trough. This structure includes a support plate 16 connected to the support frame 1, a hydraulic telescopic rod 22 fixedly connected to the top of the support plate 16, a fixed frame 29 fixedly connected to the end of the output shaft of the hydraulic telescopic rod 22, and an adjusting wheel 23 movably connected to the top of the fixed frame 29. A pressure sensor 28 is fixedly connected to the top of the fixed frame 29, and the pressure sensor 28 contacts the adjusting wheel 23. Through the setting of the pressure sensor 28, the force applied by the chain 2 to the adjusting wheel 23 can be detected in real time. Based on the detection result, it can be determined whether the chain 2 is loose. When the chain 2 is loose, the hydraulic telescopic rod 22 drives the adjusting wheel 23 to move upward, thus adjusting the tension of the chain 2. Furthermore, the adjusting wheel 23 is located below the two applicator wheels 21, so adjusting the tension of the chain 2 will not affect the operation of other components in the conveyor.

[0042] A cleaning structure is located below the support frame 1. This structure includes two guide wheels 15, a drive wheel 27 located between the two guide wheels 15, an exhaust plate 26 located between the two guide wheels 25, a cleaning brush 24 located below the drive wheel 27, a vision sensor 18 located below the support frame 1, and a collection box 10. The exhaust plate 26, drive wheel 27, and cleaning brush 24 are all located within the inner cavity of the collection box 10. The exhaust plate 26 is located above the drive wheel 27. The chain 2 is located between the drive wheel 27 and the cleaning brush 24, with the drive wheel 27 meshing with the chain 2. The top of the guide wheel 25 contacts the bottom of the chain 2. The vision sensor 18 can detect the chain 2, enabling timely cleaning.

[0043] The exhaust plate 26 has a hollow structure, and exhaust holes are provided on both sides of the inner cavity of the exhaust plate 26. One end of the exhaust plate 26 is provided with a compressed air inlet pipe 12, and the other end of the compressed air inlet pipe 12 is located outside the collection box 10. With the exhaust plate 26, when compressed air enters the exhaust plate 26 through the compressed air inlet pipe 12, compressed air can be sprayed from both sides of the exhaust plate 26. The compressed air sprayed from the exhaust plate 26 toward the uncleaned part of the chain 2 can achieve pre-cleaning of the chain 2, and the compressed air sprayed from the exhaust plate 26 toward the cleaned chain 2 can achieve drying of the chain 2. Furthermore, both sides of the cleaning structure are provided with lubrication structures.

[0044] The handle of the cleaning brush 24 is hollow. Drainage holes are evenly provided on the outer side wall of the inner cavity of the cleaning brush 24 handle. One end of the cleaning brush 24 handle is movably connected to the liquid inlet pipe 11.

[0045] A rotating shaft 34 is movably connected inside the inner cavity of the collection box 10. A cleaning brush 24 is movably connected to the outer ring of the rotating shaft 34. An electromagnet 33 is fixedly connected to the rotating shaft 34. The electromagnet 33 is in contact with the inner wall of the cleaning brush 24. When the electromagnet 33 is energized, the electromagnet 33 and the cleaning brush 24 are magnetically attracted. A servo motor 30 is fixedly connected inside the inner cavity of the collection box 10. The rotating shaft 34 is driven by the servo motor 30. A drain pipe is provided on one side of the bottom of the inner cavity of the collection box 10. When the servo motor 30 rotates, it can drive the rotating shaft 34 to rotate. The rotating shaft 34 can drive the cleaning brush 24, which is magnetically attracted to the electromagnet 33, to rotate. The cleaning brush 24 can clean the chain 2 in contact with it. By controlling the number of electromagnets 33 energized, a specific chain 2 can be cleaned.

[0046] All electrical components involved in this application are prior art. Those skilled in the art understand their connection methods. With the help of those skilled in the art, all electrical components in this application and their compatible power supplies can be connected by wires. According to the actual situation, a suitable controller can be selected to meet the control requirements. For specific connections and control sequences, please refer to the description below. The electrical connection between each electrical component is completed in the order of operation. The detailed connection methods are well known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control.

[0047] The present application will be further described below through an embodiment.

[0048] First, the pallet outbound task is generated and sent to outbound station 13. The stacker crane corresponding to outbound station 13 receives the outbound task instruction and moves along the ground rail to the corresponding racking location in the automated warehouse. The stacker crane extends its forks to remove the pallet from the racking location and places it on the stacker crane's loading platform. Then, the stacker crane moves to the outbound station and extends its forks to place the pallet to be outbound onto the chain conveyor. At this time, the chain conveyor's chain plates are at the head of the chain conveyor, and the pallet is placed exactly between the two chain plates 4. After the goods are placed, the photoelectric switch is triggered. After the photoelectric trigger is triggered, the signal is transmitted to the PLC (Programmable Logic Controller). The PLC controls the contactor to turn on. After the contactor is turned on, the motor is powered on and runs forward. The chain 2 drives the chain plates 4 to move simultaneously, transporting the pallet to the picking position of the outbound station. The operator uses a manual hydraulic trolley to drive onto the chain conveyor's chain plates and pull the entire pallet of goods directly away to complete the outbound task.

[0049] Similarly, when the outbound task is for a single or multiple items, the stacker crane receives the task and repeats the above outbound action. When the pallet arrives at the picking position on the platform, the pallet will hit the stop correction block 6 at the tail of the chain conveyor for position correction. Then, the operator will remove the required single or multiple items from the pallet. After the picking is completed, the operator will click the picking completion button. The chain conveyor will drive the chain plate 4 and the pallet containing the remaining goods to reverse. The chain plate 4 and the pallet will follow the chain conveyor to the stacker crane's picking and placing position. At this time, the chain conveyor head is also equipped with a stop correction block 6. When the pallet returns to the warehouse on the chain conveyor, it will also hit the stop correction block for position correction. After the position correction is completed, the stacker crane extends its forks to place the pallet in the original storage location of the automated warehouse rack for continued storage, waiting for the next outbound.

[0050] During the operation of the conveyor, the lubrication structure can determine whether there is abnormal noise in the chain 2 through the sound sensor 19. When there is abnormal noise in the chain 2, the lubrication structure sprays lubricating oil to lubricate the chain 2 and eliminate the abnormal noise caused by the dryness of the chain 2. If the chain 2 still produces abnormality after lubrication, the lubrication structure uploads the result to the PLC, and the PLC uploads it to the staff so that the staff can troubleshoot the fault in time.

[0051] The vision sensor 18 monitors the chain 2 in real time. When the chain 2 needs to be cleaned, the cleaning structure works, using water and compressed air to clean the chain 2 simultaneously, and then drying and applying lubricating oil to the cleaned chain 2.

[0052] In summary, this Type I chain conveyor, used in conjunction with automated storage and retrieval systems (AS / RS) racks, stacker cranes, and outbound platforms, can correct the position of the same pallet frequently entering and exiting the warehouse. This effectively prevents pallet tipping due to misalignment or displacement, while also reducing the frequency of stacker crane alarms during loading and unloading, significantly improving stacker crane operating efficiency and overall AS / RS inbound and outbound efficiency. It also retains the ability for operators to manually remove pallets from the chain conveyor using hydraulic trolleys, further enhancing the overall versatility of the chain conveyor.
