Description

[0038] Please refer to Figures 1 to 9 , the present invention provides a fork feeding device 100, which includes a frame 10, a sorting device 30, a feeding device 20, and an adjusting device 40. The frame 10 provides support and an installation foundation for the entire fork feeding device 100. The sorting device 30 is arranged on the frame 10 and outputs materials along the transmission direction. It includes a plurality of driving motors 31 and multiple groups of transmission roller groups 32 arranged in sequence along the transmission direction. The plurality of driving motors 31 are in one-to-one transmission connection with the multiple groups of transmission roller groups 32, so that the multiple groups of transmission roller groups 32 transport materials at different speeds. The feeding device 20 is arranged on the frame 10, and the feeding device 20 quantitatively transports materials to the sorting device 30 along the transmission direction. The adjusting device 40 is arranged on the feeding device 20 and / or the sorting device 30 and cooperates with the feeding device 20 and / or the sorting device 30 to adjust the posture of the materials.

[0039] In this embodiment, the material is specifically the fork in canned products. The material and specific structure of the fork are not limited. The fork feeding device 100 can batch-transport the forks out of the device in a unified posture and with a basically uniform spacing. Among them, the feeding device 20 regularly transports materials to the sorting device 30 according to a preset amount to ensure the continuous and stable operation of the sorting device 30. The sorting device 30 drives each transmission roller group 32 to rotate through the operation of the driving motor 31. Since different driving motors 31 can be set with different operating parameters, the multiple groups of transmission roller groups 32 rotate at different speeds. When the materials are placed on the transmission roller groups 32, the transmission roller groups 32 with different speeds will apply different forces to the materials, so that the materials continuously adjust their positions and spacing during the transmission process to achieve uniform discharging. The adjusting device 40 cooperates with the feeding device 20 and / or the sorting device 30 to make the materials be driven to have a unified posture during the transportation process. Specifically in this embodiment, multiple forks are discharged at intervals that are basically uniform with their handles (i.e., the length direction of the forks) parallel to the transmission direction for subsequent processing or packaging and other processes.

[0040] The design of the fork loading device 100 provided by the present invention significantly improves loading efficiency. Compared to traditional manual loading, it can quickly and stably transport large amounts of material evenly, meeting the needs of large-scale production. The precise adjustment of the material's posture by the adjustment device 40 ensures smooth subsequent processing and packaging, reducing problems such as material jamming and irregular packaging caused by material dislocation, thereby improving product quality.

[0041] Further, see Figures 4 to 7 The material sorting device 30 also includes a cross-belt transmission mechanism 33, and each drive motor 31 is respectively connected to the corresponding transmission roller group 32 through the cross-belt transmission mechanism 33. Each transmission roller group 32 includes a plurality of transmission rollers 321 arranged side by side in the transmission direction, and each transmission roller 321 is rotatably installed on the frame 10 around a rotation axis perpendicular to the transmission direction. The cross-belt transmission mechanism 33 includes a drive shaft 331 and a plurality of cross belts 332. The drive motor 31 is driven and connected to the drive shaft 331 to drive the drive shaft 331 to rotate around a rotation axis extending along the transmission direction. One end of each cross belt 332 is sleeved on the rotating shaft, and the other end of each cross belt 332 is sleeved on the corresponding transmission roller 321.

[0042] In this embodiment, after the drive motor 31 is activated, it drives the drive shaft 331 of the cross-belt transmission mechanism 33 to rotate. Specifically, it drives the drive shaft 331 to rotate about an axis extending in the transmission direction. As the drive shaft 331 rotates, the cross-belt 332 mounted thereon moves accordingly. Since the other ends of the cross-belt 332 are mounted on corresponding drive rollers 321, the movement of the cross-belt 332 drives the drive rollers 321 to rotate about an axis perpendicular to the transmission direction. The multiple drive rollers 321 rotate synchronously, thereby driving the material placed on them. The drive shaft 331, cross-belt 332, and drive rollers 321 transmit power through friction. Preferably, the surfaces of the drive shaft 331 and drive rollers 321 are rubber-coated for more stable power transmission. Furthermore, the surfaces of the drive shaft 331 and drive rollers 321 may be recessed with annular grooves for the cross-belt 332 to be inserted into, thereby preventing axial displacement of the cross-belt 332 during operation of the cross-belt transmission mechanism 33. The unique winding method of the cross belt 332 ensures synchronization and stability among the transmission rollers 321 during operation. The speeds of the different transmission rollers 321 within the same transmission roller group 32 are guaranteed to be consistent, thereby precisely separating the front and rear materials and ultimately delivering materials with consistent spacing. Even under high-speed operation or varying loads, each transmission roller group 32 maintains stable, differentiated speeds, ensuring smooth and accurate material delivery.

[0043] Further, if Figure 7As shown, the cross-belt drive mechanism 33 further includes a driving pulley 333, a driven pulley 334, a transmission belt 335, and two bearings 336. The two bearings 336 are spaced apart in the transmission direction and are respectively detachably mounted on the frame 10. The drive shaft 331 is rotatably supported by the two bearings 336. The driven pulley 334 is coaxially sleeved on the drive shaft 331 and is located between the two bearings 336. Each drive motor 31 is drivingly connected to the driving pulley 333, and the transmission belt 335 is sleeved on the driving pulley 333 and the driven pulley 334.

[0044] In this embodiment, when the drive motor 31 operates, it drives the driving pulley 333 to rotate at a high speed. The driving pulley 333 and the driven pulley 334 are connected by the transmission belt 335. Under the action of the transmission belt 335, the rotation of the driving pulley 333 transmits power to the driven pulley 334, causing the driven pulley 334 to rotate synchronously. The driven pulley 334 is sleeved on the drive shaft 331 and is coaxially connected to the drive shaft 331, thereby driving the drive shaft 331 to rotate. The drive shaft 331 then drives each transmission roller 321 in the transmission roller group 32 through the cross-belt drive mechanism 33. In this embodiment, the two bearings 336 are spaced apart and mounted on the frame 10 in the transmission direction, providing stable rotational support for the drive shaft 331, reducing the wobbling and friction of the drive shaft 331 during rotation, and ensuring that power can be smoothly transmitted to the transmission roller group 32. It can be understood that in this fork loading device 100, the cross-belt 332 is prone to aging and deformation after long-term use and needs to be frequently maintained and replaced. In this embodiment, when the cross-belt 332 needs to be maintained and replaced, only the bearings 336 need to be disassembled, and the drive shaft 331 can be removed, facilitating the maintenance and replacement operations of wear parts such as the cross-belt 332 and the transmission belt 335, improving the maintenance efficiency of the fork loading device 100, and reducing the maintenance cost.

[0045] The sorting device 30 adjusts the posture of the fork through various means. Specifically, as Figure 2 and Figure 5 shown, among the multiple groups of transmission roller groups 32, one of the transmission roller groups 32 is an adjustment roller group 322, and the material conveying area width of the adjustment roller group 322 is smaller than that of the adjacent transmission roller group 32 in the transmission direction.

[0046] In this embodiment, the material conveying area refers to the area where each transmission roller group 32 is used to carry materials. Generally, it should be located above each transmission roller group 32, and each transmission roller group 32 should have at least one side without a limiting structure so that the materials can fall. The width of the material conveying area is the dimension of the material conveying area perpendicular to the transmission direction. The design of the adjustment roller group 322 ensures that forks with different postures fall from the material sorting device 30 and no longer continue to be conveyed forward. The special design of the adjustment roller group 322 plays a key role in the alignment degree of the materials. It can further refine the material sorting process, effectively correct the problem of inconsistent postures of the materials during transmission, make the postures of the materials more consistent when the spacing is widened, and facilitate the subsequent widening of the material spacing through the cooperation of multiple groups of transmission roller groups 32. Specifically, it is preferred that the adjustment roller group 322 is the second group among multiple groups of transmission roller groups 32 in the transmission direction. In this way, the materials entering the material sorting device 30 are first conveyed forward through the first group of transmission roller groups 32, then pass through the adjustment roller group 322 to remove the materials with inconsistent postures, such as forks with the handle direction not parallel to the transmission direction, and then the remaining materials are accurately spaced apart by the subsequent multiple groups of drive rollers 321, and finally evenly discharged.

[0047] Further, please continue to refer to Figure 2 and Figure 5 , the adjusting device 40 includes an adjusting wheel 41 arranged above the adjusting roller group 322. The adjusting wheel 41 is rotatably installed on the frame 10 and is arranged side by side with the lower drive roller 321. A material passing gap is defined between the adjusting wheel 41 and the lower drive roller 321. The adjusting wheel 41 is arranged at the front end of the adjusting roller group 322 in the transmission direction.

[0048] In this embodiment, before the materials enter the adjusting roller group 322, they will first pass through the material passing gap between the adjusting wheel 41 and the lower drive roller 321. The adjusting wheel 41 is rotatably installed on the frame 10 and is arranged side by side with the lower drive roller 321. The material passing gap is designed to allow only single materials to pass through smoothly. When the materials pass through the filtering gap, the adjusting wheel 41 will contact the materials and push the stacked materials flat to ensure that the materials do not overlap, which is convenient for the subsequent adjusting roller group 322 to remove the materials with inconsistent postures, and for the subsequent multiple groups of transmission roller groups 32 to cooperate to widen the spacing between the materials and evenly discharge the materials.

[0049] Specifically, please refer to Figure 6 and Figure 7, the frame 10 includes a fixed frame 11 and a movable frame 12. Each conveying roller group 32 is rotatably installed on the movable frame 12. The movable frame 12 is arranged relative to the fixed frame 11 to be rotatable about a rotating shaft extending along the conveying direction with an adjustable position. The sorting device 30 further includes a baffle 34 fixedly sleeved on a plurality of driving rollers 321. Each driving roller 321 has a first section 341 located between the baffle 34 and the movable frame 12, and a second section 342 located on the side of the baffle 34 facing away from the movable frame 12. The end of the second section 342 far from the baffle 34 has no limiting measure, so that the materials with inconsistent postures can fall. An annular groove is formed on the first section 341, and each cross belt 332 is sleeved in the corresponding annular groove to realize the transmission of the driving roller 321. The upper part of the second section 342 constitutes a material conveying area for conveying materials.

[0050] In this embodiment, the design of the baffle 34 separates the materials from structures such as the cross belt 332 on one hand, avoiding the obstruction of the rotation and operation of each conveying roller group 32 by the materials. On the other hand, it ensures that the materials fall from the side of the material conveying area opposite to the baffle 34, facilitating the unified recovery and treatment of the fallen materials. More importantly, by adjusting the rotation position of the movable frame 12 relative to the fixed frame 11 about the rotating shaft extending along the conveying direction, the inclination angle of the conveying roller group 32 can be changed. That is to say, the material conveying area does not necessarily need to be set in a horizontal direction, but can be appropriately inclined downward towards the side where the baffle 34 is located according to actual needs. In this way, if the materials passing through the roller group 322 still have a slightly inconsistent posture, during the subsequent conveying process, they can lean against the baffle 34 due to the gravity, achieving the purpose of adjusting the posture of the materials and making the discharging postures of the materials consistent. Among them, there are various rotation adjustment structures of the movable frame 12 relative to the fixed frame 11. For example, the two are connected by a plurality of hinges with adjustable angles. In this way, the inclination angles of the conveying roller group 32 and the baffle 34 relative to the fixed frame 11 can be adjusted according to actual production needs, achieving the best balance between the consistency of the discharging postures of the materials and the conveying efficiency.

[0051] In order to achieve precise spacing adjustment of the materials, further, please refer to Figure 4 and Figure 5, the fork feeding device 100 further includes a control device and a detection device 60. The detection device 60 includes a plurality of detection components 61 mounted on the baffle 34. The plurality of detection components 61 are arranged above multiple groups of conveying roller groups 32 and are spaced apart in the conveying direction. The control device is electrically connected to the detection device 60 and multiple drive motors 31 to adjust the power of each drive motor 31 according to the detection results of the detection device 60. Specifically, each detection component 61 detects information such as the conveying speed and the front and rear spacing of the materials conveyed by each conveying roller group 32 below, and controls the speed change of each group of conveying roller groups 32 according to actual needs to gradually separate the stacked or juxtaposed materials, and finally make the materials form a certain interval, with a neat posture and fast output. The specific type of the detection component 61 is not limited. For example, it can be an image sensor, a photoelectric sensor, etc. Among them, the detection component 61 is arranged on the baffle 34, and together with the baffle 34 and multiple groups of conveying roller groups 32, it is adjustably mounted on the fixed frame 11 through the movable frame 12, so that when adjusting the inclination angles of the conveying roller group 32 and the baffle 34 relative to the fixed frame 11 according to needs during actual production, the detection accuracy of the detection component 61 is not affected.

[0052] In this embodiment, the coordinated work of the control device and the detection device 60 realizes the intelligent and automatic control of the fork feeding device 100. Through real-time monitoring and precise adjustment, various problems that occur during the conveying of materials, such as material blockage and inconsistent spacing, can be timely discovered and solved. This not only improves the feeding accuracy and stability, ensures the continuity of the production process, but also reduces manual intervention, lowers the labor intensity, and improves the production efficiency.

[0053] Based on the above embodiments, please refer to Figure 1 , Figure 8 and Figure 9 , the fork feeding device 100 provided by the present invention further includes a feeding device 20. Specifically, the feeding device 20 includes a first conveyor belt 21, a second conveyor belt 22, a third conveyor belt 23, and a fourth conveyor belt 24 arranged in sequence along the conveying direction. Among them, the first conveyor belt 21 extends in the horizontal direction and is arranged side by side with the material sorting device 30. The fork feeding device 100 further includes a guide plate 50 straddling between the first conveyor belt 21 and the material sorting device 30. The guide plate 50 extends obliquely downward from the material sorting device 30 to the first conveyor belt 21. The upper end side of the guide plate 50 is located below the adjusting roller group 322, and the lower end side of the guide plate 50 is located above the first conveyor belt 21.

[0054] In this embodiment, as Figure 2As shown, the first conveyor belt 21 constitutes the feeding station of the fork feeding device 100. The material is placed on the first conveyor belt 21. The first conveyor belt 21 extends in the horizontal direction and runs continuously, driving the material to move towards the direction close to the sorting device 30, so as to realize the feeding of the sorting device 30. The design of the guide plate 50 enables a large amount of materials falling from the adjusting roller set 322 to directly fall back to the feeding station and be conveyed to the sorting device 30 again by the first conveyor belt 21, achieving the purpose of automatically recycling materials and improving production efficiency.

[0055] Further, please refer to Figure 9 , the feeding device 20 further includes a fourth conveyor belt 24. The fourth conveyor belt 24 is located between the first conveyor belt 21 and the sorting device 30 in the transmission direction. The adjusting device 40 includes a guiding member 42 disposed on the upper side of the fourth conveyor belt 24. The guiding member 42 defines a guiding channel 421 extending along the transmission direction. The width of the guiding channel 421 gradually decreases in the transmission direction, and the end of the guiding channel 421 is connected to the front end of the sorting device 30.

[0056] In this embodiment, after the material enters the fourth conveyor belt 24, it continues to move forward under the drive of the fourth conveyor belt 24. The guiding member 42 on the upper side of the fourth conveyor belt 24 defines a guiding channel 421 extending along the transmission direction and with a gradually decreasing width. As the material moves in the guiding channel 421, due to the gradually narrowing channel width, the spacing between the materials is gradually compressed. At the same time, the material is restricted by both sides of the guiding member 42 and is forced to adjust its posture, and the direction of the material tends to be consistent. When the material moves to the end of the guiding channel 421, the materials with basically the same direction smoothly enter the front end of the sorting device 30. In this way, the materials are sorted into a consistent direction and enter the sorting device 30 in an orderly manner through the guiding channel 421, which facilitates the subsequent sorting device 30 to further adjust the posture of the materials and reduces the difficulty of the sorting device 30 to output materials with the same posture and consistent spacing.

[0057] Preferably, please refer to Figure 1, the feeding device 20 further includes a second conveyor belt 22 and a third conveyor belt 23 arranged in sequence in the conveying direction. The second conveyor belt 22 extends upward from the end of the first conveyor belt 21. A plurality of limiting plates 221 are protruded at intervals along the upper side of the second conveyor belt 22 in the conveying direction. The end of the second conveyor belt 22 extends above the front end of the third conveyor belt 23. The third conveyor belt 23 is arranged between the end of the second conveyor belt 22 and the front end of the fourth conveyor belt 24, and the end of the third conveyor belt 23 extends above the front end of the material guiding channel 421. In this embodiment, the plurality of limiting plates 221 on the second conveyor belt 22 divide the upper side thereof into a plurality of accommodating spaces. Due to the height design of the limiting plates 221, the number of materials accommodated in each accommodating space is substantially the same, so as to realize the feeding to the sorting device 30 in a substantially quantitative manner. In addition, through the orientation design between the second conveyor belt 22 and the third conveyor belt 23, and between the third conveyor belt 23 and the fourth conveyor belt 24, on the one hand, the material conveying direction is adjusted so that it turns from the loading station and then enters the sorting device 30, which is convenient for the layout of the guiding plate 50. On the other hand, the materials fall and disperse step by step under the action of the height difference, which is convenient for the subsequent sorting operation.

[0058] The overall working process of the fork feeding device 100 will be described below. When the fork feeding device 100 works, when the fork feeding device 100 works, it enters the upwardly extending second conveyor belt 22 from the end of the first conveyor belt 21. The design of the limiting plates 221 on the second conveyor belt 22 causes the materials higher than the limiting plates 221 to slide back onto the first conveyor belt 21 again. After the materials reach the end of the second conveyor belt 22, they fall onto the third conveyor belt 23, and the materials are more dispersed. Then, they are turned by the third conveyor belt 23 and further fall and disperse above the front end of the fourth conveyor belt 24. The guiding members 42 on the upper side of the fourth conveyor belt 24 define a material guiding channel 421 that extends along the conveying direction and gradually narrows in width. When the materials move on the fourth conveyor belt 24, as the width of the material guiding channel 421 becomes narrower, the spacing between the materials is compressed, the posture is adjusted, and the material direction gradually tends to be consistent until it moves to the end of the material guiding channel 421 and is ready to enter the sorting device 30.

[0059] The material enters the material sorting device 30. The material sorting device 30 includes multiple groups of conveying roller groups 32. The driving motor 31 drives the conveying roller groups 32 to rotate through the crossed belt transmission mechanism 33. The multiple groups of conveying roller groups 32 transport the material at different speeds to gradually increase the spacing between the materials. Specifically, one of the conveying roller groups 32 is the adjustment roller group 322, and the width of its material conveying area is smaller than that of the adjacent conveying roller groups 32. Before the material enters the adjustment roller group 322, the stacked material is pushed flat by the adjustment wheel 41 to ensure that the materials do not overlap. Then the material passes through the adjustment roller group 322, and the materials with inconsistent postures further fall from the adjustment roller group 322, drop onto the lower guide plate 50, and are transported back to the first conveyor belt 21 through the guide plate 50 to supply the material sorting device 30 again.

[0060] The remaining materials continue to be conveyed backward through the multiple groups of conveying roller groups 32. The detection component 61 above the multiple groups of conveying roller groups 32 detects information such as the conveying speed and the front and rear spacing of the materials transported by each of the lower conveying roller groups 32, and controls the speed change of each group of conveying roller groups 32 according to actual needs to gradually separate the stacked or juxtaposed materials. During this process, the inclined design of the multiple groups of conveying roller groups 32 and the baffle 34 causes the materials with slightly inconsistent postures to lean against the baffle 34, and finally the materials are output with a certain interval, neat postures, and quickly.

[0061] The above are only the preferred embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structures made by using the specification and drawings of the present invention, directly or indirectly applied in other related technical fields, are similarly included in the patent protection scope of the present invention.
