[0001] This application relates to the field of conveying, specifically to a feeding device. Background Technology

[0002] Currently, when conveying workpieces, a motor-driven conveyor belt is typically used to transport the workpiece from one end to the other for loading or unloading. For workpieces requiring positioning, fixtures must be installed on the conveyor belt to hold them in place. However, installing fixtures on existing conveyor belts is quite difficult. Utility Model Content

[0003] In view of the above, it is necessary to propose a feeding device that can be equipped with a support for positioning workpieces, and the installation method is relatively simple.

[0004] This application provides a feeding device, comprising: a base; a feeding assembly including two feeding wheels, a feeding belt, and multiple mounting components, wherein the two feeding wheels are spaced apart at both ends of the base, each feeding wheel includes a wheel body and stop portions disposed on opposite sides of the wheel body, the feeding belt is sleeved on the outer periphery of the two wheel bodies and located between the two stop portions, and the multiple mounting components are spaced apart on the feeding belt along the transmission direction of the feeding belt; multiple carriers, respectively disposed on the multiple mounting components, each carrier including a connecting portion and a carrier portion for positioning a workpiece, the connecting portion being disposed on one side of the carrier portion and connected to the corresponding mounting component, wherein the connecting portion partially extends between the two stop portions when moving to the feeding wheel; and a feeding drive, disposed on the base and connected to one of the feeding wheels, for driving the connected feeding wheel to rotate the feeding belt, so that the feeding belt drives the carrier and the workpiece on the carrier to move from one end of the base to the other end of the base.

[0005] In some embodiments, the outer peripheral surface of the wheel body is provided with equidistant grooves for wheel teeth along the circumferential direction, and the inside of the feed belt is provided with equidistant boss wheel teeth, the grooves for wheel teeth being used to accommodate the boss wheel teeth.

[0006] In some embodiments, the base includes a support body, and the feeding assembly further includes a feeding shaft rotatably disposed on the support body and a tensioning member. The feeding wheel is disposed on the feeding shaft, one end of the tensioning member is connected to the support body, and the other end of the tensioning member is disposed on the feeding shaft. When one end of the tensioning member moves, the other end of the tensioning member can drive the feeding shaft to move, so as to tension the feeding belt.

[0007] In some embodiments, the feeding assembly further includes a guide member disposed on the support body, and a limiting groove is formed on one side of the guide member, wherein a portion of the feeding belt and a portion of the mounting member can rotate within the limiting groove.

[0008] In some embodiments, the feeding device further includes a transmission assembly, which includes a support member, a drive wheel, a driven wheel, and a transmission belt. The support member is disposed on the base, the drive wheel and the driven wheel are spaced apart and rotatably disposed on the support member, the driven wheel is coaxially disposed with one of the feeding wheels, the transmission belt is sleeved on the outer periphery of the drive wheel and the driven wheel, and the feeding drive member is drivenly connected to the drive wheel.

[0009] In some embodiments, the feeding drive includes a motor and a reducer, the motor and the reducer being connected, and the reducer being connected to the drive wheel.

[0010] In some embodiments, the feeding assembly further includes a plurality of origin-finding sensors, which are respectively disposed on a plurality of the carrier parts. Each origin-finding sensor is used to send a movement duration signal when the corresponding carrier part moves a preset distance, so that the movement duration signal is compared with a standard duration signal to determine whether the movement process of the carrier part is abnormal.

[0011] In some embodiments, the feeding assembly further includes a sensing sensor disposed on one side of the support body, for transmitting a trigger sensing signal toward the moving carrier portion to determine whether the carrier portion carries the workpiece.

[0012] In some embodiments, the feeding assembly further includes an offset sensor disposed on one side of the support body, for transmitting an offset sensing signal toward the moving carrier portion to determine whether the workpiece on the carrier portion is offset.

[0013] In some embodiments, the supporting portion includes a supporting plate and a positioning block. The positioning block is disposed on the supporting plate, and the supporting plate is disposed between the positioning block and the connecting portion. The supporting plate is used to support the workpiece, and the positioning block is used to insert into the workpiece to position the workpiece.

[0014] The aforementioned feeding device, by installing a carrier portion on the feeding belt, allows the carrier portion to position the workpiece, enabling the feeding belt to transport the positioned workpiece. The installation of the carrier portion is relatively simple by setting an mounting component on the feeding belt and attaching it to a connecting portion that connects to the carrier portion. Since part of the connecting portion extends between the two stop portions when it moves to the feeding wheel, while the other part of the connecting portion is located outside the feeding wheel, the carrier portion connected to the connecting portion is located on one side of the feeding wheel and has a gap between it and the feeding wheel. When the feeding belt rotates, the carrier portion will not interfere with the feeding wheel, ensuring smooth rotation of the feeding belt. Attached Figure Description

[0024] The following will describe some embodiments of this application in detail with reference to the accompanying drawings.

[0025] Please see Figure 1 This application provides a feeding device 100 for conveying workpieces (not shown), including a base 10, a feeding assembly 20, multiple carriers 30 and a feeding drive 40.

[0026] In this embodiment, the feeding assembly 20, multiple carriers 30 and feeding drive 40 are arranged in two groups side by side on the base 10.

[0027] Please see also Figure 2 and Figure 3The feeding assembly 20 includes two feeding wheels 21, a feeding belt 22, and multiple mounting parts 23. The two feeding wheels 21 are spaced apart at both ends of the base 10. Each feeding wheel 21 includes a wheel body 211 and a stop portion 212 located on opposite sides of the wheel body 211. The wheel body 211 has a cylindrical structure, and the stop portion 212 has a sheet-like structure. The feeding belt 22 is sleeved on the outer periphery of the two wheel bodies 211 and located between the two stop portions 212. The mounting parts 23 have a block-like structure, and multiple mounting parts 23 are spaced apart on the feeding belt 22 along the transmission direction of the feeding belt 22. Multiple carriers 30 are respectively disposed on multiple mounting members 23. Each carrier 30 includes a connecting part 31 and a supporting part 32 for positioning the workpiece. The connecting part 31 is a plate-shaped structure, located on one side of the supporting part 32 and connected to the corresponding mounting member 23. In this embodiment, the connecting part 31 is bolted to the corresponding mounting member 23. When the connecting part 31 moves to the feeding wheel 21, part of it extends between the two stop parts 212. A feeding drive 40 is disposed on the base 10 and connected to one of the feeding wheels 21. The drive 40 drives the connected feeding wheel 21 to rotate the feeding belt 22, so that the feeding belt 22 moves the carrier 30 and the workpiece on the carrier 30 from one end of the base 10 to the other end of the base 10.

[0028] In use, the operator places the workpiece on the support part 32 from one end of the feeding belt 22. Then, the feeding drive 40 drives the connected feeding wheel 21 to rotate the feeding belt 22, so that the feeding belt 22 moves the support part 30 and the workpiece on the support part 30 from one end of the base 10 to the other end of the base 10. Another operator takes the workpiece from the other end of the base 10 to load or unload it.

[0029] The aforementioned feeding device 100, by installing a support portion 32 on the feeding belt 22, allows the support portion 32 to position the workpiece, thus enabling the feeding belt 22 to transport the positioned workpiece. By providing a mounting member 23 on the feeding belt 22 and mounting the mounting member 23 to a connecting portion 31 connected to the support portion 32, the installation of the support member 30 is relatively simple. Since part of the connecting portion 31 extends between the two stop portions 212 when it moves to the feeding wheel 21, the other part of the connecting portion 31 is located outside the feeding wheel 21. Therefore, the support portion 32 connected to the connecting portion 31 is located on one side of the feeding wheel 21 and has a gap between it and the feeding wheel 21. When the feeding belt 22 rotates, the support portion 32 will not interfere with the feeding wheel 21, ensuring smooth rotation of the feeding belt 22 and avoiding friction-induced motion resistance.

[0030] In some embodiments, the outer periphery of the wheel body 211 is provided with circumferentially spaced tooth grooves 2111, and the interior of the feed belt 22 is provided with equidistant boss teeth 221. The boss teeth 221 engage with the tooth grooves 2111, and the tooth grooves 2111 are used to accommodate the boss teeth 221. The engagement of the boss teeth 221 and the tooth grooves 2111 in transmitting power can reduce power transmission losses, lower costs, effectively control the running distance of the feed belt 22, achieve more precise control, and meet the requirements of automated high-precision and high-accuracy displacement control.

[0031] Please see also Figure 4 In some embodiments, the base 10 includes a receiving body 11 and a support body 12 disposed on one side of the receiving body 11, the receiving body 11 being a frame-shaped structure. The feeding assembly 20 also includes a feeding shaft 24 rotatably disposed on the support body 12 and a tensioning member 25, the feeding wheel 21 being disposed on the feeding shaft 24, the tensioning member 25 being plate-shaped, one end of the tensioning member 25 being connected to the support body 12, and the other end of the tensioning member 25 being sleeved on the feeding shaft 24, the movement of one end of the tensioning member 25 can cause the other end of the tensioning member 25 to drive the feeding shaft 24 to move, thereby increasing the distance between the two feeding wheels 21 and tensioning the feeding belt 22. In this embodiment, a snap ring mounting groove is provided on the feeding shaft 24, and the middle part of the wheel body 211 is composed of a snap ring locking assembly, the wheel body 211 being used to be installed in the snap ring mounting groove of the feeding shaft 24 through the snap ring locking assembly, thereby realizing a fixed connection between the wheel body 211 and the feeding shaft 24. After the tensioning member 25 moves, it can be fixed to the support body 12 with bolts. In this embodiment, the support body 11 is composed of aluminum profiles, balance feet, frame connecting blocks, corner brackets, etc. The balance feet contact the ground and adjust the level of the logistics line. The frame connecting blocks are used to connect with the main equipment and the customer supply machine, which can improve the stability of the feeding belt 22.

[0032] In some embodiments, the feeding assembly 20 further includes a guide 26, which is plate-shaped and disposed on the support body 12. A limiting groove 261 is formed on one side of the guide 26, allowing a portion of the feeding belt 22 and a portion of the mounting member 23 to rotate within the limiting groove 261. By providing the guide 26, the movement of the feeding belt 22 can be guided, improving the running accuracy of the feeding belt 22 and preventing the carrier 30 from swaying up and down during operation, thus affecting the moving accuracy of the carrier 30.

[0033] Please see also Figure 5In some embodiments, the feeding device 100 further includes a transmission assembly 50, which includes a support member 51, a drive wheel 52, a driven wheel 53, and a transmission belt 54. The support member 51 is plate-shaped and is disposed on the base 10. The drive wheel 52 and the driven wheel 53 are vertically spaced and rotatably disposed on one side of the support member 51. The driven wheel 53 is coaxially arranged with the feeding wheel 21. The transmission belt 54 is sleeved on the outer periphery of the drive wheel 52 and the driven wheel 53. The feeding drive member 40 is drivenly connected to the drive wheel 52. In this embodiment, the tooth specifications of the drive wheel 52 and the driven wheel 53 match the belt grooves of the transmission belt 54, which can improve the accuracy and efficiency of power transmission.

[0034] In some embodiments, the feeding drive 40 includes a motor 41 and a reducer 42, which are connected together. The reducer 42 is connected to the drive wheel 52. By driving the drive wheel 52 with the motor 41 and the reducer 42, precise displacement and on-demand start / stop of the feeding belt 22 can be achieved. Furthermore, the power of the motor 41 can be reduced, and the reducer 42 can proportionally reduce the required power source, effectively reducing power source cost.

[0035] In some embodiments, the feeding assembly 20 further includes a plurality of origin-finding sensors 27, which are respectively disposed on a plurality of carrier parts 32. Each origin-finding sensor 27 is used to send a movement duration signal when the corresponding carrier part 32 moves a preset distance, so that the movement duration signal is compared with a standard duration signal to determine whether the movement process of the carrier part 32 is abnormal. In this embodiment, the origin-finding sensor 27 is disposed on an origin-finding bracket, which is disposed on one side of the corresponding carrier part 32. Since the spacing of each carrier 30 on the feeding belt 22 is consistent, and the running interval of the feeding belt 22 is consistent, the entire feeding belt 22 is in its original position when the movement of the feeding belt 22 ends. By setting a origin-finding sensor 27, the origin-finding sensor 27 sends a movement duration signal when the corresponding carrier part 32 moves one carrier member 30 interval. The movement duration signal is compared with the standard duration signal of the carrier part 32 moving one carrier member 30 interval, thereby determining whether the movement process of the carrier part 32 is abnormal. If it is abnormal, the operating parameters of the feeding belt 22 need to be adjusted to ensure that the entire feeding belt 22 is in its original position when the movement of the feeding belt 22 ends.

[0036] In some embodiments, the feeding assembly 20 further includes a sensing sensor 28, which is disposed on one side of the support 12 and is used to emit a trigger sensing signal toward the moving carrier 32 to determine whether there is a workpiece on the carrier 32. In this embodiment, the sensing sensor 28 can be a photoelectric sensor, which is disposed on a sensing bracket, which is disposed on the support 12. By setting the sensing sensor 28, a trigger sensing signal can be emitted toward the moving carrier 32 to determine whether there is a workpiece on the carrier 32. Specifically, there are multiple sensing sensors 28, which can be disposed at both ends and the middle of the support 12.

[0037] In some embodiments, the feeding assembly 20 further includes an offset sensor 29, which is disposed on one side of the support 12 and is used to emit an offset sensing signal toward the moved carrier 32 to determine whether the workpiece on the carrier 32 is offset. In this embodiment, the offset sensor 29 can be a photoelectric sensor, which can emit an offset sensing signal toward a fixed position to determine whether the workpiece on the carrier 32 is offset. Specifically, there are multiple offset sensors 29, which can be disposed at both ends and the middle of the support 12.

[0038] Please continue reading Figure 2 In some embodiments, the supporting part 32 includes a supporting plate 321 and a positioning block 322. The positioning block 322 is disposed on the supporting plate 321, and the supporting plate 321 is disposed between the positioning block 322 and the connecting part 31. The supporting plate 321 is used to support the workpiece, and the positioning block 322 is used to insert into the workpiece to position the workpiece. In this embodiment, there are two positioning blocks 322, which are disposed at opposite ends of the supporting plate 321, and are used to insert into the workpiece to position the workpiece.

[0039] The implementation process of the feeding device 100 in this application embodiment is as follows:

[0040] The operator places the workpiece on the bearing part 32 from one end of the feeding belt 22, and the positioning block 322 is inserted into the workpiece to position it. Then the motor 41 and the reducer 42 drive the drive wheel 52 to rotate, the drive wheel 52 drives the transmission belt 54 to rotate, the transmission belt 54 drives the driven wheel 53 to rotate, the driven wheel 53 drives the feeding wheel 21 to rotate, and the feeding wheel 21 drives the feeding belt 22 to rotate, so that the feeding belt 22 moves the bearing part 30 and the workpiece on the bearing part 30 from one end of the base 10 to the other end of the base 10. Another operator takes the workpiece from the other end of the feeding belt 22 to load or unload it.
