Description

Technical Field

[0001] This utility model belongs to the technical field of feeding equipment, specifically relating to a dual-station feeding device. Background Technology

[0002] With the increasing demand for high-speed manufacturing, high efficiency has become the mainstream choice for modern production lines. In the field of precision manufacturing, workpiece processing often requires multiple continuous operations. Feeding devices can realize the synchronous operation of "feeding-processing" and improve the production line cycle time. Therefore, feeding devices are being chosen by more and more people. However, existing feeding devices only operate at one station, which leads to low overall equipment efficiency and is not suitable for the current demand to improve production efficiency. At the same time, when transporting materials, the coordination between the feeding device and the feeding trolley also needs to be paused and waited, resulting in slow and unsmooth feeding response speed, which is difficult to meet the rhythm requirements of high-speed automated production lines. Therefore, to solve these problems, we propose a dual-station feeding device. Utility Model Content

[0003] This utility model provides a dual-station feeding device to solve at least one of the above-mentioned technical problems.

[0004] The technical solution adopted by this utility model is as follows: a dual-station feeding device, including a frame with a first feeding station and a second feeding station, wherein the first feeding station and the second feeding station are provided with a horizontal pulling mechanism and a lifting mechanism that cooperate with the feeding trolley, the feeding trolley has multiple stacked material trays, and the material trays have a horizontal pulling slot on the side facing the frame; the horizontal pulling mechanism includes a moving component for horizontally pulling the material trays and a pin component that cooperates with the horizontal pulling slot; the lifting mechanism includes a lifting plate placed below the bottommost material tray and a lifting component that drives the lifting plate to move.

[0005] In a preferred embodiment, the moving component includes a horizontal pull plate and a horizontally arranged linear guide rail. The pin assembly is connected to the horizontal pull plate, and the horizontal pull plate is connected to a horizontal lead screw. The horizontal lead screw drives the pin assembly to reciprocate along the linear guide rail through the horizontal pull plate. The pin assembly includes a base plate and a buckle disposed on the base plate, wherein the buckle is an L-shaped fixing block.

[0006] In a preferred embodiment, the buckle further includes a T-shaped locking block that cooperates with the horizontal pull latch and an adjuster for controlling the opening and closing of the T-shaped locking block, wherein the T-shaped locking block includes a first locking block and a second locking block.

[0007] In a preferred embodiment, the moving component further includes a rack structure disposed on the frame and a Z-shaped plate connected to the pin assembly, wherein the rack structure drives the pin assembly to reciprocate along the linear guide rail.

[0008] In a preferred embodiment, the moving component further includes a guide rail, which includes a plurality of support columns and a pulley assembly disposed on the support columns. The pulleys of the pulley assembly are provided with limiting edges to limit the position of the tray.

[0009] In a preferred embodiment, the guide rail is provided with limiting baffles at both ends to limit the horizontal movement distance of the moving component.

[0010] In a preferred embodiment, the lifting assembly includes a vertically arranged column guide rail and a vertical lead screw for adjusting the height. The vertical lead screw is connected to the lifting support plate via a slider, allowing it to move vertically along the column guide rail.

[0011] In a preferred embodiment, the lifting plate is provided with a positioning pin and an elastic element, and the material tray is provided with a round hole that mates with the positioning pin.

[0012] In a preferred embodiment, the elastic element includes a base block disposed on the side of the lifting plate facing the material tray, a spring block hinged to the base block, and a spring connecting the base block and the spring block, so as to buffer the pressure exerted by the lifting plate on the material tray by the spring.

[0013] Due to the adoption of the above technical solution, the beneficial effects achieved by this utility model are as follows: 1. As a preferred embodiment of this utility model, by setting up a dual-station feeding device, the feeding efficiency is improved. Furthermore, through the cooperation of the horizontal pulling mechanism and the lifting mechanism on the feeding device, the precise gripping, transfer, and positioning of the material tray is achieved. Specifically, the horizontal pulling mechanism uses the horizontal movement of the moving component and the locking action of the pin component to pull the material tray laterally out of the feeding trolley; the lifting mechanism drives the lifting plate through the lifting component to adjust the vertical height of the material tray. This design, with the two mechanisms working together and combined with the dual-station design, enables alternating feeding, effectively improving feeding efficiency and reducing equipment waiting time.

[0014] 2. In a preferred embodiment of this utility model, the precise gripping and transfer of the material tray is achieved through the mechanical transmission of the moving component and the structural cooperation of the pin component. Specifically, when the horizontal lead screw rotates, it drives the horizontal pull plate to move horizontally on the linear guide rail through the threaded transmission, providing power and guidance for the pin component; the L-shaped fixing block of the pin component uses its shape to form a mechanical engagement with the horizontal pull slot of the material tray, thereby pulling the material tray laterally from the initial position and transferring it to the target position under the drive of the moving component, realizing the horizontal transfer of materials.

[0015] Furthermore, precise positioning of the material tray is achieved by setting up T-shaped locking blocks and an adjuster. Specifically, the adjuster controls the opening and closing of the first and second locking blocks to separate or engage with the horizontal locking slot of the material tray. The friction and positioning constraint generated by the T-shaped locking blocks ensure more stable lateral movement of the tray, thereby improving the stability and efficiency of the transfer.

[0016] 3. In a preferred embodiment of this utility model, a gear structure further enables smooth transfer of the moving component. Specifically, one end of the Z-shaped plate is securely connected to the pin assembly, and the other end is connected to the gear. When the gear rotates, the meshing of the gear and rack causes the gear to move linearly along the rack direction, thereby driving the pin assembly to move back and forth along the linear guide rail, realizing the gripping and transfer of the material tray. Compared with screw drive, this transmission method has higher transmission efficiency and stronger driving force.

[0017] 4. As a preferred embodiment of this utility model, the purpose of guiding and limiting is achieved by setting a guide rail. Specifically, through the coordinated action of the support column, pulley block and limiting edge, the material pallet is ensured to maintain a stable linear motion trajectory during the transfer process. The pulley block reduces the friction force during pallet transfer and improves the efficiency of the transfer process.

[0018] Meanwhile, the limiting edge of the pulley prevents the pallet from shifting or shaking during horizontal transfer, ensuring that the pallet can move accurately to the designated position along the preset path, thus ensuring the safety and stability of the feeding device.

[0019] 5. In a preferred embodiment of this utility model, the vertical movement of the material tray is achieved by setting a screw drive and a guide rail on the lifting assembly. Specifically, the vertical screw provides lifting power to the lifting tray through threaded transmission; the column guide rail provides precise guidance for the movement of the lifting tray, restricting its movement to only the vertical direction. The slider connected to the vertical screw drives the lifting tray to move smoothly vertically along the column guide rail, thereby achieving precise adjustment of the height of the material tray.

[0020] 6. In a preferred embodiment of this utility model, the positioning and cushioning of the material tray are achieved by setting a positioning pin and an elastic element. The positioning pin, through its cooperation with the circular hole of the material tray, ensures the precise positioning of the tray.

[0021] Meanwhile, the elastic component utilizes the compression and rebound characteristics of springs to buffer the impact force on the material tray during the lifting and moving process, preventing the tray from shaking or being damaged due to uneven force, thereby improving the stability and reliability of the loading process.

[0029] Example 1: A preferred embodiment, such as Figure 1As shown, a dual-station loading device includes a frame 1 with a first loading station and a second loading station. A loading trolley loaded with multiple stacked loading pallets 8 is pushed to either the first or second loading station of the frame 1, aligning the horizontal pull slot 81 of the loading pallet 8 facing the frame 1 with the pin assembly 4 of the horizontal pull mechanism 2. Simultaneously, it ensures that the bottom loading pallet 8 is positioned above the lifting plate 6. The lifting mechanism 5 includes the lifting plate 6 positioned below the bottom loading pallet 8 and a lifting assembly 7 that drives the lifting plate 6 to move. Subsequently... The lifting mechanism 5 is activated by lifting component 7, which drives lifting plate 6 to move upward, raising the bottommost material tray 8 and all the material trays 8 above it to a certain height, so that the topmost material tray 8 is aligned with the horizontal pulling mechanism 2, preparing for the horizontal pulling of the material tray 8. The horizontal pulling mechanism 2 includes a moving component 3 for horizontal pulling of the material tray 8 and a pin component 4 that cooperates with the horizontal pulling slot 81. As the material tray 8 moves upward, the pin component 4 is inserted into the horizontal pulling slot 81 of the material tray 8 to lock the material tray 8. Subsequently, the moving component 3 is activated, driving the pin component 4 and the material tray 8 locked to it to move horizontally into the frame 1, pulling the material tray 8 from the original loading trolley position to the designated loading position in the frame 1, completing one loading action. After one layer of material trays 8 is pulled away, the lifting mechanism 5 and the horizontal pulling mechanism 2 repeat the above lifting and horizontal pulling actions, and so on, until all the material trays 8 on the loading trolley are pulled into the frame 1 to complete the loading. When all the material trays 8 on the loading trolley of the first loading station have been loaded, the operation can be moved to the second station to continue loading, while replenishing the loading trolley of the first station. This cycle is repeated to improve the loading efficiency.

[0030] Example 2: like Figures 2-4As shown, a dual-station loading device, differing from Embodiment 1, includes a moving component 3 comprising a horizontal pull plate 31 and a horizontally arranged linear guide rail 32. The horizontal pull plate 31 is connected to a horizontal lead screw 33. As the multi-layered stacked material trays 8 rise, the moving component 3 moves towards the loading trolley. When the multi-layered stacked material trays 8 are in place, because the engaging part of the horizontal pull slot 81 matches the shape of the bottom surface of the L-shaped fixing block 421, the horizontal part of the L-shaped fixing block 421 inserts into the horizontal groove of the horizontal pull slot 81, while the vertical part abuts against the edge of the horizontal pull slot 81, forming a stable engaging structure. This firmly connects the pin assembly 4 to the material tray 8, providing a reliable connection foundation for subsequent transfer operations. After the L-shaped fixing block 421 engages with the horizontal pull-out latch 81, the horizontal lead screw 33 rotates. Since the horizontal pull plate 31 and the horizontal lead screw 33 are connected by a threaded connection, under the axial force generated by the rotation of the lead screw, the horizontal pull plate 31 is driven to move along the horizontally set linear guide rail 32 towards the inside of the frame 1. The linear guide rail 32 provides stable guidance for the horizontal pull plate 31, ensuring the accuracy of its movement trajectory and reducing deviation and shaking. Since the L-shaped fixing block 421 is engaged with the material tray 8, the horizontal pull plate 31 is fixedly connected to the base plate 41 of the horizontal pull plate 31 pin assembly 4. The movement of the horizontal pull plate 31 transmits the force through the base plate 41, pulling the material tray 8 laterally out of the loading trolley. During the movement, the material tray 8 slides smoothly along the guide rail 34 until it is transferred to the designated position inside the frame 1. When the material tray 8 is moved into place, the horizontal lead screw 33 rotates in the opposite direction, driving the horizontal pull plate 31 and the pin assembly 4 back to the initial position along the linear guide rail 32. During the return process, the pin assembly 4 returns to the initial state, waiting for the next grabbing of the new material tray 8. This cycle repeats to achieve continuous and stable material feeding and transfer.

[0031] In addition, the buckle 42 also includes a T-shaped locking block 422 and an adjuster 423. When the moving component 3 moves to the upper material trolley, the adjuster 423 controls the T-shaped locking block 422 to be in the open state. At this time, the first locking block 4221 and the second locking block 4222 are separated from each other, and a gap sufficient to accommodate the thickness of the horizontal pull slot 81 is formed between them. When the multi-layer stacked material tray 8 is in place, the adjuster 423 controls the open first locking block 4221 and the second locking block 4222 to move towards each other and gradually close. As the locking blocks close, the two side walls of the T-shaped locking block 422 are gradually embedded into the groove of the horizontal pull slot 81 until they fit tightly. A stable locking structure is formed between the T-shaped locking block 422 and the horizontal pull slot 81, which can withstand the pulling force generated when the horizontal pull mechanism 2 pulls the tray later, ensuring that the tray will not fall off during the transfer process.

[0032] Example 3: like Figure 2As shown, a dual-station feeding device, different from Embodiment 1, has a rack structure 35 fixedly installed on the frame 1, with the gear and rack in a meshing state. One end of the Z-shaped plate 36 is connected to the base plate 41 of the pin assembly 4, and the other end is connected to the gear transmission mechanism. When the device is started, due to the meshing relationship between the gear and rack, the gear is constrained by the rack during rotation and cannot rotate in place. It can only move linearly along the direction of the rack. The linear movement of the gear is transmitted to the base plate 41 through the connecting component Z-shaped plate 36, causing the base plate 41 to move synchronously on the linear guide rail 32. When the feeding is completed, the gear rotates in the opposite direction, and the base plate 41 is driven to return to the initial position along the linear guide rail 32 through the Z-shaped plate 36. This cycle repeats to achieve continuous and stable feeding and conveying.

[0033] Example 4: like Figure 2 and Figure 5 As shown, a dual-station feeding device, differing from Embodiment 1, includes a guide rail 34 for the moving component 3. Multiple support columns 341 are securely fixed to the frame 1, providing solid support for the pulley assembly 342. The pulley assembly 342 is mounted on the support columns 341, allowing the pulleys to rotate flexibly. When the latch 42 of the pin assembly 4 engages with the horizontal pull slot 81 of the material tray 8, the horizontal screw 33 drives the horizontal pull plate 31 to move the base plate 41. Simultaneously, the pulleys of the pulley assembly 342 begin to rotate under the push of the base plate 41, causing the following tray to roll against the rail, greatly reducing the friction during tray transfer. The resistance during the process allows the pallet to move more smoothly on the guide rail 34. At this time, the side of the pallet contacts the limiting edge 343 of the pulley block 342. Due to the presence of the limiting edge 343, the pallet's movement path in the horizontal direction is limited, and it can only move in a straight line along the arrangement direction of the pulley block 342. Whether due to uneven driving force of the horizontal pulling mechanism 2 or slight vibration caused by the external environment, the limiting edge 343 always constrains the pallet from the side to prevent the pallet from shifting to the left or right. This design further ensures the smoothness and straightness of the pallet movement, and ensures the stability and efficiency of the pallet movement.

[0034] At the same time, such as Figure 5 As shown, the guide rail 34 is equipped with limiting baffles 344 at both ends to limit the horizontal movement distance of the moving component 3. As the moving component 3 moves, when it contacts the limiting baffles 344, the limiting baffles 344, due to their rigid structure, generate a reverse blocking force on the moving component 3. Since the limiting baffles 344 are fixed on the pulley block 342, this blocking force can quickly prevent the moving component 3 from moving forward and stop it at the preset limit position. This design effectively prevents the moving component 3 from accidentally causing the material tray 8 to fall off the predetermined track, ensuring the safe operation of the feeding device.

[0035] Example 5: like Figure 1 As shown, a dual-station feeding device, different from embodiment 1, has the vertical lead screw 72 in its initial state when the feeding trolley is in place. The slider 73 and the lifting tray 6 connected to it are located directly below the bottom material tray 8. The column guide rail 71 is fixedly installed on the frame 1 to provide stable support and guidance for the vertical movement of the lifting tray 6.

[0036] When the feeding device is started, the vertical lead screw 72 begins to rotate. Since the lead screw and slider 73 are connected by a thread, according to the lead screw transmission principle, the rotational motion of the lead screw is converted into linear motion of the slider 73 along the lead screw axis. As the vertical lead screw 72 rotates, the slider 73 slides upward along the column guide rail 71. The slider 73 connects to the lifting pallet 6, thereby driving the lifting pallet 6 to rise synchronously. During the rising process, the guiding structure of the column guide rail 71 ensures that the slider 73 and the lifting pallet 6 can only move in the vertical direction, effectively limiting horizontal displacement. When the lifting pallet 6 rises to the preset height... When the horizontal pull slot 81 of the material tray 8 and the pin assembly 4 of the horizontal pull mechanism 2 are in the optimal matching position, the vertical screw 72 stops rotating. At this time, the slider 73 and the lifting plate 6 are fixed in the current position. The horizontal pull mechanism 2 pulls the material tray 8 out horizontally. After the horizontal pull mechanism 2 completes the horizontal transfer of the material tray 8, it returns to move towards the loading trolley. At the same time, the lifting assembly 7 starts to move upward again, and the material tray 8 is smoothly sent upward again. This cycle is repeated until the material tray 8 of the loading trolley is completely transported. This design continuously provides stable vertical height adjustment support for the loading process.

[0037] Example 6: like Figure 6 As shown, a dual-station feeding device, different from Embodiment 1, when the lifting component 7 is activated and the lifting pallet 6 rises to a certain height, the positioning pin 61 on the lifting pallet 6 is accurately inserted into the corresponding round hole 82 at the bottom of the material tray 8, thereby positioning the material tray 8. The combination of the two restricts the displacement of the material tray 8 in the left and right horizontal directions, ensuring that the tray rises vertically in subsequent operations without shifting. When the material tray 8 rises to the correct position, the horizontal pulling mechanism 2 is activated, and the positioning pin 61 is pressed down into the slot of the lifting pallet 6 along with the movement of the tray and the rotating shaft, so that the horizontal pulling mechanism 2 smoothly moves the lifting pallet 6.

[0038] Meanwhile, when the lifting pallet 6 rises to a certain height, as the pallet gradually approaches the material placement tray 8, the spring block 622 of the elastic element 62 first contacts the bottom surface of the tray. At this time, the tray applies downward pressure to the spring block 622. Since the spring block 622 is connected to the bottom block 621 through a hinge, under the action of pressure, the spring block 622 begins to rotate around the hinge point. At the same time, the spring 623 is compressed, buffering the impact force generated on the material placement tray 8 when the lifting pallet 6 rises, ensuring that the tray rises smoothly and avoiding the tray shaking or being damaged due to excessive impact force.

[0039] Example 7: like Figure 2 As shown, a dual-station feeding device, different from Embodiment 1, has a rack structure 35 fixedly installed on the frame 1, with the gear and rack in a meshing state. One end of the Z-shaped plate 36 is connected to the base plate 41 of the pin assembly 4, and the other end is connected to the gear transmission mechanism. When the device is started, due to the meshing relationship between the gear and rack, the gear is constrained by the rack during rotation and cannot rotate in place. It can only move linearly along the direction of the rack. The linear movement of the gear is transmitted to the base plate 41 through the connecting component Z-shaped plate 36, causing the base plate 41 to move synchronously on the linear guide rail 32. When the feeding is completed, the gear rotates in the opposite direction, and the base plate 41 is driven to return to the initial position along the linear guide rail 32 through the Z-shaped plate 36. This cycle repeats to achieve continuous and stable feeding and conveying.
