Description

Technical Field

[0001] The utility model relates to the technical field of visual inspection automation equipment, in particular to a feeding mechanism for a fruit detection line. Background Art

[0002] Traditional fruit sorting relies on manual labor. Workers visually inspect and manually grade fruits based on experience, which is time-consuming and laborious. With the development of technology, the fruit sorting process increasingly depends on automated and intelligent systems, which can improve sorting speed, accuracy, and efficiency, while also reducing labor costs. Modern fruit sorting lines use mechanical equipment and machine vision technology. Through high-speed cameras and image processing systems, machine vision technology can identify the characteristics of fruits. Using optical sensors, it can also detect the color, shape, and surface defects of fruits to achieve fast and accurate sorting.

[0003] In the existing automated fruit sorting lines, after fruits are placed in fruit trays, they will be transported to the visual inspection area by a feeding mechanism. Currently, in order to ensure a certain distance between adjacent fruit trays during transportation to avoid stacking, the driving motor on the feeding transmission line is intermittently started and stopped by setting relays, etc. This not only causes waste of the energy consumption of the driving motor, but also cannot strictly ensure that there is a certain distance between adjacent fruit trays, and it is particularly prone to congestion when guiding into the visual processing transmission line. Summary of the Utility Model

[0004] The technical problem to be solved by the utility model is: to overcome the deficiencies in the prior art and provide a feeding mechanism for a fruit detection line.

[0005] The technical solution adopted by the utility model to solve its technical problem is: a feeding mechanism for a fruit detection line, including a bracket. A transmission component is arranged on the bracket. A spiral feeding component is arranged on the bracket on one side of the transmission component. The spiral feeding component includes a spiral feeding rod and a power component for driving the spiral feeding rod to rotate. The pitch of the spiral feeding rod gradually increases from the inlet of the transmission component to the outlet of the transmission component. A guiding component is arranged at the discharging place of the spiral feeding component. The guiding component has a guiding disc driven to rotate by the power component. A plurality of limiting notches for limiting fruit trays are evenly arranged on the outer circle of the guiding disc.

[0006] Further, the transmission component includes a reduction motor, a transmission frame, and a flexible chain plate. The transmission frame includes a main shaft and a sub-shaft rotatably connected to both ends inside the transmission frame. An active sprocket and a driven sprocket are respectively installed on the main shaft and the sub-shaft. A flexible chain plate is sleeved between the active sprocket and the driven sprocket. The output end of the reduction motor is connected to one end of the main shaft through a coupling.

[0007] Furthermore, one side of the transfer rack is provided with a guardrail, and the other side of the transfer rack is a spiral pusher rod. A protective cover with a "C" - shaped structure is arranged outside the spiral pusher rod.

[0008] Further, the feeding component further includes a mounting bracket, a guiding seat, and a first rotating shaft. The guiding seat includes a bottom plate fixed on the top surface of the mounting bracket and a guiding plate connected to one section of the outer edge of the bottom plate. The guiding plate is arc - shaped, and the curvature of this arc - shaped guiding plate is the same as that of the feeding tray. One end of the first rotating shaft passes through the top surface of the mounting bracket and is connected to the feeding tray through a mounting sleeve.

[0009] Furthermore, the upper end of the first rotating shaft has an extended shaft head section. A seal is arranged between the shaft head section and the mounting sleeve. Synchronous belt pulley three and synchronous belt pulley four are sequentially installed at the lower end of the first rotating shaft.

[0010] Furthermore, the power component includes a power source, a first synchronous belt pulley, a second rotating shaft, and a second synchronous belt pulley. The power source is connected to the first synchronous belt pulley through a transition piece. The first synchronous belt pulley is connected to the fourth synchronous belt pulley through a synchronous belt. The upper end of the second rotating shaft is connected to a 90 - degree angle converter through a universal joint coupling. The 90 - degree angle converter is connected to one end of the spiral pusher rod. The lower end of the second rotating shaft is installed with a second synchronous belt pulley. The second synchronous belt pulley is connected to the third synchronous belt pulley through a synchronous belt.

[0011] Furthermore, there are 1 - 2 guiding synchronous belt pulleys arranged inside the synchronous belt loops around the first synchronous belt pulley and the fourth synchronous belt pulley, and inside the synchronous belt loops around the second synchronous belt pulley and the third synchronous belt pulley.

[0012] The beneficial effects of the present utility model are as follows:

[0013] A spiral pushing component is added on one side of the existing feeding and transfer component to apply a radial external force to the fruit trays on the feeding and transfer component, so as to increase the transfer distance between adjacent fruit trays. Moreover, the pitch of the spiral pusher rod of the spiral pushing component increases successively from the inlet of the transfer component to the outlet of the transfer component, which can ensure that the transfer distance between adjacent fruit trays is larger when approaching the outlet of the transfer component, thus avoiding the congestion situation when the fruit trays are transferred into the feeding component. The spiral pusher rod and the feeding tray are driven by the same power component, which is convenient for control. Brief Description of the Drawings

[0027] As Figure 1 and Figure 2 shown, a feeding mechanism for a fruit detection line includes a bracket 1, a transmission assembly 2 is arranged on the bracket 1, and a spiral feeding assembly 3 is arranged on the bracket 1 on one side of the transmission assembly 2. The spiral feeding assembly 3 includes a spiral feeding rod 31 and a power assembly for driving the rotation of the spiral feeding rod 31. The pitch of the spiral feeding rod 3 gradually increases from the inlet of the transmission assembly 2 to the outlet of the transmission assembly 2. A guiding assembly 4 is arranged at the discharging position of the spiral feeding assembly 3. The guiding assembly 4 has a guiding disk 41 driven by the power assembly to rotate, and a plurality of limiting notches 411 for limiting the fruit trays 13 are evenly arranged on the outer circle of the guiding disk 41.

[0028] Specifically, the transmission assembly 2 includes a reduction motor 21, a transmission frame 22, and a flexible chain plate 23. The transmission frame 22 includes a main shaft 221 and a sub-shaft 222 rotatably connected to both ends inside the transmission frame 22. A driving sprocket (not shown in the figure) and a driven sprocket (not shown in the figure) are respectively installed on the main shaft 221 and the sub-shaft 222. A flexible chain plate 23 is sleeved between the driving sprocket and the driven sprocket. The output end of the reduction motor 21 is connected to one end of the main shaft 221 through a coupling. A guardrail 223 is arranged on one side of the transmission frame 22. Generally, there are guardrails on both sides of the existing transmission frame 22, but on the other side of the transmission frame 22 in this embodiment is the spiral feeding rod 31, and a "C"-shaped protective cover 32 is arranged outside the spiral feeding rod 31. The protective cover 32 can play a role in protecting the spiral feeding rod 31 and prevent the spiral feeding rod 31 from being directly exposed to external forces and affecting its performance.

[0029] The power assembly includes a power source 7, a first synchronous belt pulley 8, a second rotating shaft 9, and a second synchronous belt pulley 10. The power source 7 is connected to the first synchronous belt pulley 8 through a transition piece (configured according to the transmission requirements of the entire production line. It can be that the power source 7 drives a sprocket assembly to drive a certain mechanism to act, and a synchronous belt pulley is installed on the rotating or rotating part of this mechanism). The first synchronous belt pulley 8 is connected to the fourth synchronous belt pulley 6 through a synchronous belt. The upper end of the second rotating shaft 9 is connected to a 90-degree angle converter 12 through a universal joint coupling 11. The 90-degree angle converter 12 is connected to one end of the spiral feeding rod 31. The lower end of the second rotating shaft 9 is installed with the second synchronous belt pulley 10, and the second synchronous belt pulley 10 is connected to the third synchronous belt pulley 5 through a synchronous belt.

[0030] In addition, considering the transmission of force during transmission, 1 to 2 guiding synchronous belt pulleys are provided inside the synchronous belt loops around the synchronous belt pulley one 8 and the synchronous belt pulley four 6, and inside the synchronous belt loops around the synchronous belt pulley two 10 and the synchronous belt pulley three 5.

[0031] As Figure 3 shown, the material guiding assembly 4 further includes a mounting bracket 42, a guiding seat 43 and a first rotating shaft 44. The guiding seat 43 includes a bottom plate 431 fixed to the top surface of the mounting bracket 42 and a guiding plate 432 connected to a section of the outer edge of the bottom plate 431. The guiding plate 432 is arc-shaped, and the curvature of the arc-shaped guiding plate 432 is the same as that of the material guiding disc 41. When the fruit tray 13 rotates with the material guiding disc 41, the guiding plate 432 prevents the fruit tray 13 from falling off and can also play an auxiliary guiding role. One end of the first rotating shaft 44 passes through the top surface of the mounting bracket 42 and is connected to the material guiding disc 41 through a mounting sleeve 45. The first rotating shaft 44 is connected to the material guiding disc 41 through the mounting sleeve 45, and the mounting height can be adjusted by mounting sleeves 45 of different specifications. More specifically: the upper end of the first rotating shaft 44 has a protruding shaft head section 441, and a sealing member 46 is provided between the shaft head section 441 and the mounting sleeve 45. With such a setting, the connection effectiveness between the first rotating shaft 44 and the material guiding disc 41 can be ensured. The synchronous belt pulley three 5 and the synchronous belt pulley four 6 are sequentially installed at the lower end of the first rotating shaft 44.

[0032] Specific operation process: The fruit tray 13 is placed on the transmission assembly 2 manually or by a machine. The reduction motor 21 drives the main shaft 221 to rotate, and the driving sprocket rotates accordingly, so that the flexible chain plate 23 drives the fruit tray 13 to move. At this time, the power source 7 of the power assembly is started, driving the synchronous belt pulley one 8 to rotate. Through the belt, the synchronous belt pulley four 6 rotates, the first rotating shaft 44 rotates, driving the material guiding disc 41 to rotate. At the same time, the synchronous belt pulley three drives the synchronous belt pulley two 10 to rotate through the belt, so that the second rotating shaft 9 rotates, and then drives the spiral pusher 31 to rotate through the 90-degree angle converter 12. The spiral pusher 31 applies a radial force to the fruit tray 13 moving on the flexible chain plate 23, so that the distance between adjacent fruit trays 13 is widened. The fruit tray 13 moves to the material guiding disc 41 and enters the limiting notch 411 on the material guiding disc 41, and rotates with the material guiding disc 41 to the next transmission line.

[0033] What is described in the above specification is only the specific implementation manners of the present utility model. Various examples do not constitute limitations to the substantial content of the present utility model. Those of ordinary skill in the art to which the present utility model pertains can make modifications or variations to the previously described specific implementation manners after reading the specification, without departing from the essence and scope of the utility model.
