Description

Technical Field

[0001] This invention belongs to the field of transportation, and more specifically, relates to an elevator transfer system and an elevator transfer control method. Background Technology

[0002] Currently, the air conditioning manufacturing industry generally adopts a multi-story warehouse structure and forklift-elevator collaborative transfer in the finished product storage and delivery process. Its core process can be divided into two stages: storage and delivery, both of which heavily rely on manual forklift operation and elevator resource scheduling.

[0003] Storage Stage: After the finished air conditioners are assembled on the final assembly line, they need to go through the following key steps: Palletizing: The finished air conditioners are stacked on pallets according to the order specifications by palletizing robots to form standardized transport units (usually 8-20 air conditioners per pallet); The whole pallet of finished products is transported to the temporary buffer area by roller conveyor line, waiting for forklift dispatch. The forklift transports the palletized finished products to the elevator, and then vertically transports them to the designated storage floor. The forklift picks up the finished products from the elevator and transfers them to the storage position to complete the warehousing.

[0004] Shipping stage: Reverse outbound process. After an order is placed, the warehouse starts the outbound operation according to the dispatch instructions. The forklift picks up the goods from the designated floor, and the finished product is clamped by the forklift and transferred to the first floor shipping area by elevator, thus completing the shipment.

[0005] Technical shortcomings of the traditional model: The existing multi-story warehouse structure and forklift and elevator collaborative transfer mode have significant defects in terms of efficiency, cost and safety, which have become a bottleneck restricting the upgrading of logistics in the air conditioning manufacturing industry. Summary of the Invention

[0006] The purpose of this invention is to provide an elevator transfer system and an elevator transfer control method, which aims to solve the problem of low production efficiency caused by using a forklift to grab items into the elevator and transporting them to different floors.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] In a first aspect, the elevator transfer system provided by the present invention includes:

[0009] An elevator, which has a car;

[0010] A docking and conveying mechanism is installed inside the car and is used to transport items to different floors during the operation of the elevator.

[0011] A buffer conveyor is installed outside the elevator doors on each floor of the warehouse to transfer items between the docking conveyor and the forklift.

[0012] Furthermore, the docking and conveying mechanism includes:

[0013] Connecting to the conveyor line;

[0014] The guide rail and the slider are slidably connected, the slider is fixedly connected to the docking conveyor line, and the guide rail is fixedly connected to the car.

[0015] A moving drive unit, installed on the docking conveyor line, is used to drive the docking conveyor line and the slider to move along the extension direction of the guide rail, thereby causing the docking conveyor line to move closer to or further away from the buffer conveying mechanism.

[0016] Furthermore, the moving drive component is a hydraulic cylinder.

[0017] Furthermore, the buffer conveying mechanism includes a buffer conveying line and a loading conveying line. The loading conveying line is used to transfer items between the buffer conveying line and the forklift, and the buffer conveying line is used to transfer items between the docking conveying mechanism and the loading conveying line.

[0018] Furthermore, the buffer conveyor line is configured as multiple lines, which are arranged adjacent to each other in sequence.

[0019] Furthermore, the feeding conveyor line and / or the buffer conveyor line are provided with detection elements for detecting the presence of the item.

[0020] Furthermore, the detection element is any one or any combination of photoelectric sensors, proximity sensors, and weight sensors.

[0021] Furthermore, the buffer conveying mechanism is equipped with a barcode scanner, which is used to identify the QR code on the item to obtain floor information.

[0022] Secondly, the elevator transfer control method provided by the present invention is applied to the elevator transfer system described above, including:

[0023] Control the elevator to move to the first floor and open the elevator door located on the first floor;

[0024] The docking conveyor connects to the buffer conveyor located on the first floor, so that items placed on the buffer conveyor by the forklift can be transferred to the docking conveyor through the buffer conveyor.

[0025] Close the elevator door located on the first floor and control the elevator to move to the second floor.

[0026] Furthermore, during the process of connecting the docking conveyor with the buffer conveyor located on the first floor, the following steps are also included:

[0027] The docking conveyor line is driven to move toward the buffer conveyor by a moving drive component, thereby reducing the gap between the docking conveyor and the buffer conveyor.

[0028] Compared with existing technologies, the elevator transfer system and elevator transfer control method provided by this invention have the following advantages: Through the coordinated operation of the elevator, the docking conveyor mechanism, and the buffer conveyor mechanism, the forklift only needs to place or retrieve items from the buffer conveyor mechanism without entering the elevator. This automated production mode effectively shortens the manual delivery distance, improves the efficiency of elevator use, thereby increasing production efficiency and reducing labor costs. Simultaneously, it avoids forklifts entering the elevator, reducing the risk of damage to both forklifts and elevators, lowering maintenance costs, and eliminating safety hazards. Significant improvements have been achieved in efficiency, cost, and safety. Attached Figure Description

[0045] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0046] Currently, the air conditioning manufacturing industry generally adopts multi-story warehouse architecture and forklift-elevator collaborative transfer mode in the finished product storage and delivery process. Its core process can be divided into two stages: storage and delivery, both of which heavily rely on manual forklift operation and elevator resource scheduling.

[0047] Storage Stage: After the finished air conditioners are assembled on the final assembly line, they need to go through the following key steps: Palletizing, which is to use palletizing robots to stack the finished units on pallets according to the order specifications to form standardized transport units (usually 8-20 air conditioners per pallet); the whole pallet of finished units is transported to a temporary buffer area by roller conveyor line to wait for forklift dispatch. Then the forklifts transport the palletized finished units to the elevator, and the elevators transport them vertically to the designated storage floor. The forklifts pick up the finished units from the elevator and then transfer them to the storage location to complete the warehousing.

[0048] Shipping stage: This is a reverse outbound process. After an order is placed, the warehouse starts the outbound operation according to the dispatch instructions. Forklifts pick up the goods from the designated floor, clamp the finished product machine with the forklifts, and use the elevator to transfer the entire panel of air conditioners down to the first-floor shipping area to complete the shipment.

[0049] Technical shortcomings of the traditional model: The existing multi-story warehouse architecture and forklift-elevator collaborative transfer mode have significant defects in terms of efficiency, cost and safety, which have become a bottleneck restricting the upgrading of logistics in the air conditioning manufacturing industry.

[0050] 1. Elevator waiting bottleneck: Forklifts wait an average of 5-10 minutes per elevator ride at the elevator entrance, which affects production efficiency.

[0051] 2. Excessive inefficient handling: A single air conditioner undergoes at least 6 forklift transfers from production to shipment (production line transfer → elevator transfer → fixed floor warehousing → fixed floor warehousing → elevator waiting for transfer → warehousing and shipment).

[0052] 3. High operating costs: Five forklift drivers are required per shift, and labor costs account for 35% of the total logistics costs. In terms of equipment maintenance, the annual maintenance cost of forklifts exceeds 2 million yuan (including attachment wear and tear, battery replacement, etc.).

[0053] 4. Significant safety hazards: Forklift drivers enter and exit elevators every day, and due to operational reasons, there is a possibility of collisions with elevators, causing damage. In addition, the repeated "positioning-waiting-fine-adjustment" operation in the elevator can lead to a decrease in attention and reaction speed, posing safety hazards.

[0054] Based on this, the elevator transfer system and elevator transfer control method provided by the present invention have achieved improvements in efficiency, cost, and safety by leveraging an automated production mode.

[0055] like Figure 1 , Figure 2 As shown, the elevator transfer system provided by the present invention includes: a lifting elevator 1, a docking conveying mechanism 2, and a buffer conveying mechanism 3; wherein, the lifting elevator 1 has a car; the docking conveying mechanism 2 is located inside the car and is used to transport items 4 to different floors under the operation of the lifting elevator 1; the buffer conveying mechanism 3 is located outside the elevator doors 7 on each floor of the warehouse and is used to transfer items 4 between the docking conveying mechanism 2 and the forklift 5.

[0056] Understandably, the elevator car (1) is a box-shaped space used to carry and transport people and goods. The car generally consists of main components such as the car floor, car walls, car roof, and car doors. Additionally, item 4 can be a finished air conditioner unit, also known as a pre-assembled unit.

[0057] This invention utilizes the coordinated operation of the elevator 1, the docking conveyor 2, and the buffer conveyor 3. The forklift 5 only needs to place or retrieve items 4 from the buffer conveyor 3 without entering the elevator 1. This automated production mode effectively shortens the manual delivery distance, improves the utilization efficiency of the elevator 1, thereby increasing production efficiency and reducing labor costs. Simultaneously, it avoids the forklift 5 entering the elevator 1, reducing the risk of damage to both the forklift 5 and the elevator 1, lowering maintenance costs, and eliminating safety hazards. Significant improvements have been achieved in efficiency, cost, and safety.

[0058] like Figure 2 , Figure 3 As shown, the docking conveyor 2 includes a docking conveyor line 21, a guide rail 22, a slider 23, and a moving drive component 24; wherein, the docking conveyor line 21 is used to carry and convey the item 4; the guide rail 22 is slidably connected to the slider 23, the slider 23 is fixedly connected to the docking conveyor line 21, and the guide rail 22 is fixedly connected to the car; the moving drive component 24 is installed on the docking conveyor line 21 and is used to drive the docking conveyor line 21 and the slider 23 to move along the extension direction of the guide rail 22, thereby causing the docking conveyor line 21 to move closer to or away from the buffer conveyor 3.

[0059] This invention also considers that when item 4 is transferred between the buffer conveyor mechanism 3 and the docking conveyor line 21, a certain gap will appear at the elevator door 7. If the gap is large, for example, reaching 20cm, item 4 is likely to fall into the gap at the elevator door 7, which poses a risk of item 4 falling during the transfer process. To avoid production abnormalities, a movable docking conveyor mechanism 2 is specially made so that it can automatically dock with the buffer conveyor mechanism 3, thereby reducing the gap between the docking conveyor mechanism 2 and the buffer conveyor mechanism 3 during connection, preventing item 4 from falling, and preventing the line from jamming. Specifically, before transferring item 4, the movable drive component 24 pushes the docking conveyor line 21 and the slider 23 to move on the guide rail 22, causing the docking conveyor line 21 to move towards the buffer conveyor mechanism 3, thereby reducing the gap between the docking conveyor line 21 and the buffer conveyor mechanism 3. In this way, it can effectively prevent item 4 from falling into the gap between the docking conveyor mechanism 2 and the buffer conveyor mechanism 3 when they are connected, and also prevent the line from jamming. Similarly, after the item 4 is transferred, the moving drive 24 pushes the docking conveyor 21 and the slider 23 to move along the guide rail 22, and retracts the docking conveyor 21 into the elevator 1 to return it to its initial position so as not to affect the opening and closing of the elevator door 7.

[0060] Furthermore, the moving drive component 24 can be a hydraulic cylinder. Hydraulic cylinders offer stable output force and precise control, ensuring smooth and accurate movement of the docking conveyor line 21 and the slider 23 on the guide rail 22. This facilitates better docking and retraction operations between the docking conveyor line 21 and the buffer conveyor mechanism 3, improving the reliability and stability of the entire elevator transfer system. Moreover, hydraulic cylinders have a relatively simple structure, are easy to maintain and service, reducing system maintenance costs and ease of use.

[0061] Of course, in other alternative embodiments, the moving drive 24 may be pneumatically driven or electrically driven.

[0062] If a pneumatic drive is used, it converts the pressure energy of gas into mechanical energy to power the movement of the docking conveyor line 21 and the slider 23. Pneumatic drive has the advantages of rapid action and sensitive response, enabling it to quickly move the docking conveyor line 21 to achieve docking and retraction operations with the buffer conveyor mechanism 3, thus improving the efficiency of item transfer 4. At the same time, the pneumatic drive system is relatively clean, does not produce oil or other pollutants, is environmentally friendly, and is relatively easy to maintain.

[0063] If an electric drive system is used, a motor typically drives a transmission device, such as a lead screw or gear, which in turn drives the docking conveyor line 21 and the slider 23 to move on the guide rail 22. Electric drives offer high control precision, accurately controlling the movement distance and speed of the docking conveyor line 21 to ensure the accuracy of docking and retraction operations. Furthermore, electric drives can be programmed for automated control, facilitating integration and collaborative operation with other parts of the elevator transfer system and enhancing the system's overall intelligence.

[0064] like Figure 1 , Figure 4 and Figure 5 As shown, the buffer conveying mechanism 3 includes a buffer conveying line 31 and a loading conveying line 32. The loading conveying line 32 is used to transfer the item 4 between the buffer conveying line 31 and the forklift 5, and the buffer conveying line 31 is used to transfer the item 4 between the docking conveying mechanism 2 and the loading conveying line 32.

[0065] Understandably, the loading conveyor line 32 is installed inside the car of the elevator 1. Due to space and load-bearing limitations within the car, the loading conveyor line 32 can only transport one stack of items 4 at a time (i.e., a stack of multiple items 4). In actual production, the forklift 5 uses a tractor to transport multiple stacks of items 4. It first picks up one stack of items 4 and places it on the loading conveyor line 32. After the loading conveyor line 32 transfers the stack of items 4 to the buffer conveyor line 31, it picks up another stack of items 4 and places it on the loading conveyor line 32, and so on. At the same time, since the elevator 1 operates at a relatively slow speed, the forklift 5 can directly place the items 4 on the buffer conveyor mechanism 3 for buffering, and then it can handle other tasks, thus saving the forklift 5's waiting time.

[0066] like Figure 4 and Figure 5 As shown, there are multiple buffer conveyor lines 31, which are arranged adjacent to each other in sequence.

[0067] Understandably, the number of buffer conveyor lines 31 can be increased or decreased according to production needs. Figure 4In this system, three buffer conveyor lines 31 are configured: a first buffer conveyor line 311, a second buffer conveyor line 312, and a third buffer conveyor line 313. The third buffer conveyor line 313 is arranged adjacent to the loading conveyor line 32. These three buffer conveyor lines 31 together constitute the turnover buffer area of ​​the buffer conveyor mechanism 3, while the loading conveyor line 32 is the loading area of ​​the buffer conveyor mechanism 3. This configuration can meet the production requirement of forklift 5 to transfer four stacks of goods 4 at a time.

[0068] In addition, the feeding conveyor line 32 and / or the buffer conveyor line 31 are equipped with detection elements for detecting the presence of the item 4. The detection elements are any one or any combination of photoelectric sensors, proximity sensors and weight sensors.

[0069] By setting detection elements on the production line, the presence of item 4 can be detected, thereby controlling the start and stop of the production line. This improves the accuracy of automatic control, ensures the stability and safety of item 4 during the transfer process, reduces accidents such as item 4 falling or colliding due to abnormal operation of the production line, ensures the smooth progress of the production process, and improves production efficiency and product quality.

[0070] exist Figure 5 In the process, the feeding conveyor line 32 is equipped with a proximity sensor, and the three buffer conveyor lines 31 are all equipped with photoelectric sensors, namely photoelectric through-beam induction switches.

[0071] In addition, the buffer conveying mechanism 3 is equipped with a barcode scanner 33, which is used to identify the QR code on the item 4 to obtain floor information.

[0072] exist Figure 5 In this configuration, the barcode scanner 33 is only installed on the first buffer conveying mechanism 3.

[0073] In practical application, a barcode scanning and association system for item 4 is established. The finished goods warehouse manager first sets the storage floor and specific storage location within the floor in the system, generates a QR code, and affixes it to item 4. Forklift 5 places item 4 onto the buffer conveyor 3. When item 4 passes the barcode scanner 33 and moves to the docking conveyor 2, the scanner 33 identifies the QR code, automatically retrieves storage location information from the system's database, and automatically determines the floor where item 4 should be stored. This then controls the elevator 1 to automatically transport item 4 to the corresponding floor. At this time, the LED screen on the corresponding floor displays the storage location corresponding to item 4. After item 4 moves from the docking conveyor 2 to the buffer conveyor 3, forklift 5 unloads item 4 from the buffer conveyor 3 and transfers it to the corresponding storage location according to the location displayed on the LED screen.

[0074] Based on the above structure of the elevator transfer system, the elevator transfer control method provided by the present invention includes the following steps:

[0075] Control the elevator to move to the first floor and open the elevator door on the first floor;

[0076] The docking conveyor connects to the buffer conveyor 3 located on the first floor, so that the items placed on the buffer conveyor by the forklift can be transferred to the docking conveyor 2 through the buffer conveyor 3.

[0077] Close the elevator door on the first floor and control the elevator to move to the second floor.

[0078] This invention utilizes the coordinated operation of a lifting elevator, a docking conveyor mechanism, and a buffer conveyor mechanism. Forklifts only need to place items on or retrieve items from the buffer conveyor mechanism 3, without needing to enter the lifting elevator. This design maximizes the production line and elevator capacity, reduces forklift waiting time, lowers item stacking rates, thereby improving production efficiency and reducing labor costs. Simultaneously, it avoids forklifts entering the lifting elevator, reducing the risk of damage to both forklifts and the elevator, lowering maintenance costs, and eliminating safety hazards. Significant improvements have been achieved in efficiency, cost, and safety.

[0079] In addition, the process of connecting the docking conveyor with the buffer conveyor located on the first floor also includes:

[0080] The docking conveyor line is driven to move toward the buffer conveyor by a moving drive component, thereby reducing the gap between the docking conveyor and the buffer conveyor.

[0081] This invention creates a movable docking conveyor mechanism that can automatically dock with a buffer conveyor mechanism, thereby reducing the gap between the docking conveyor mechanism and the buffer conveyor mechanism during connection, preventing items from falling off, and preventing the production line from jamming.

[0082] To gain a deeper understanding of the present invention, a detailed description will be provided below using an elevator transfer system and elevator transfer control method from a preferred embodiment as an example.

[0083] like Figures 1 to 5 As shown, the elevator transfer system includes a lift 1 with a car, a docking and conveying mechanism 2 installed inside the car, and a buffer conveying mechanism 3 installed outside the elevator doors 7 on each floor of the warehouse.

[0084] A buffer conveyor mechanism 3 is installed outside the elevator doors 7 on the first floor (61), second floor (62), and third floor (63) of the factory building. This buffer conveyor mechanism 3 consists of a first buffer conveyor line 311, a second buffer conveyor line 312, a third buffer conveyor line 313, and a loading conveyor line 32, arranged sequentially and adjacently. The docking conveyor mechanism 2 consists of a docking conveyor line 21, guide rails 22, sliders 23, and a moving drive component 24. The docking conveyor line 21, the first buffer conveyor line 311, the second buffer conveyor line 312, and the third buffer conveyor line 313 all use plate chain conveyors, while the loading conveyor line 32 uses a roller conveyor. The first buffer conveyor line 311 is equipped with a barcode scanner 33 and a first photoelectric through-beam sensor 341; the second buffer conveyor line 312 is equipped with a second photoelectric through-beam sensor 342; the third buffer conveyor line 313 is equipped with a third photoelectric through-beam sensor 343; and the feeding conveyor line 32 is equipped with a feeding sensor 344, i.e., a proximity sensor.

[0085] Inbound control logic: After forklift 5 places the stacked item 4 onto the loading conveyor line 32, the loading sensor switch 344 detects item 4, and the loading conveyor line 32 immediately starts operating, transporting the stacked item 4 to the turnover buffer area. Upon arrival of item 4, the buffer area begins intelligent scheduling. When the first photoelectric sensor switch 341 does not detect the stacked item 4, the first buffer conveyor line 311, the second buffer conveyor line 312, and the third buffer conveyor line 313 operate simultaneously; when the first photoelectric sensor switch 341 detects item 4, the first buffer conveyor line 311 stops operating, while the second buffer conveyor line 312 and the third buffer conveyor line 313 continue operating; when the second photoelectric sensor switch 342 detects item 4, the second buffer conveyor line 312 stops operating, while the third buffer conveyor line 313 continues operating; when the third photoelectric sensor switch 343 detects item 4, the third buffer conveyor line 313 stops operating.

[0086] The control logic after exiting the elevator on other floors is mirrored. After item 4 exits the elevator, the first buffer conveyor line 311, the second buffer conveyor line 312, the third buffer conveyor line 313, and the loading conveyor line 32 begin operation. When the loading sensor switch 344 senses item 4, the loading conveyor line 32 stops, while the first buffer conveyor line 311, the second buffer conveyor line 312, and the third buffer conveyor line 313 continue operating. When the third photoelectric beam sensor switch 343 senses item 4, the third buffer conveyor line 313 stops operating, while the first buffer conveyor line 311 and the second buffer conveyor line 312 continue operating. When the second photoelectric beam sensor switch 342 senses item 4, the second buffer conveyor line 312 stops operating, while the first buffer conveyor line 311 continues operating. When the first photoelectric beam sensor switch 341 senses item 4, the first buffer conveyor line 311 stops operating.

[0087] like Figure 6 As shown, the production method of the elevator collaborative production scheduling system (i.e., the elevator operation control method) is as follows: The finished goods warehouse keeper first enters a QR code into the system and associates it with the finished goods floor and the relevant storage location within that floor. A forklift places the stacked items onto the buffer conveyor. The items then follow the buffer conveyor and the docking conveyor line into the elevator. When an item passes a barcode scanner, the scanner automatically scans the code. The scanner automatically associates the QR code with the information entered by the finished goods warehouse keeper, thereby controlling the elevator to reach the corresponding floor. After the elevator door opens, the items automatically exit the elevator, and the LED display shows the corresponding storage location. The items are then transferred to the loading conveyor line via the buffer conveyor line. When the loading conveyor line stops, the forklift picks up the items. The forklift places the items into the correct storage location according to the LED display, completing the entire warehousing process. The outbound process follows the same production operation procedure. Through bidirectional scheduling control, this system can be used not only in the storage stage but also in the shipping stage. Forklifts place items onto the production line on other floors, allowing items to be directly transferred to the first floor, thus automating storage and shipping processes.

[0088] Based on this, the present invention adopts an automated production mode, reduces the distance of manual delivery, maximizes the utilization rate of elevators, and achieves the goal of reducing the number of employees by four; through the coordinated scheduling of each process, the delivery time of a single board is successfully reduced to less than 3 minutes, and the efficiency is improved by 50%; through intelligent control of the production line, the packaging damage rate is reduced by 20%, reducing losses by 200,000 yuan; by preventing forklifts from entering the elevator, the risk of damage to forklifts and elevators is reduced (preventing forklifts from crashing into the elevator), maintenance costs are reduced, and safety hazards are eliminated.
