Description

Technical Field

[0001] This utility model relates to an optical image sorting machine, and more particularly to a spider-hand feeding mechanism for the sorting machine. Background Technology

[0002] Optical image sorting machines use spider arms for loading, which can adapt to irregularly shaped parts. They often use vibratory plates to flip the sorted objects, but the flipping efficiency is not high. There is a sorted object that is a flat plate with legs. The legs need to be facing upwards. When the legs are facing downwards, the plate will tilt or become horizontal. It is proposed to use a flipping nozzle to flip the object. Utility Model Content

[0003] In view of the technical problems existing in the background art, the present utility model aims to provide a spider hand feeding mechanism for a screening machine, which is designed with a corresponding backing plate for the material to be aligned, a flipping air nozzle to blow air, and a standing foot to drive the material to flip as a whole.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: The spider-hand feeding mechanism of the screening machine includes a rotating feeding plate, an annular baffle on the outer periphery of the feeding plate, a feeding station, a discharging station and a flipping station, a feeding station equipped with a feeding component, a discharging station equipped with a discharging component, a discharging component including a discharging conveyor belt and a spider hand, the spider hand connecting the feeding plate and the discharging conveyor belt, and a flipping station equipped with a central backing plate and an outer peripheral backing plate. The central backing plate is located at the center of the feeding plate and gradually moves away from the center of the feeding plate along the rotation direction. The outer peripheral backing plate is located on the outer periphery of the feeding plate and gradually moves closer to the center of the feeding plate along the rotation direction. Both the outer peripheral backing plate and the central backing plate are equipped with flipping air nozzles, the air outlets of the flipping air nozzles are inclined downward and the air blowing direction is consistent with the extension direction of the corresponding backing plate.

[0005] In this design, the outer peripheral support plate aligns the material on the outer ring of the feeding tray, while the central support plate aligns the material on the inner ring of the feeding tray. Air is blown through the flip nozzle. If the flat plate does not block the uprights, the uprights will be subjected to force, causing the material to flip as a whole.

[0006] Preferably, the discharge assembly further includes a camera, which is signal-connected to a controller, and the controller is control-connected to the spider arm.

[0007] In this scheme, the camera captures the orientation of the material's upright feet at the discharge station, and the controller controls the robotic arm to move the material with its upright feet facing upwards.

[0008] Preferably, the material feeding station is defined as first, the material discharging station as second, and the flipping station is located after the material discharging station.

[0009] In this scheme, after the material is discharged, the feeding tray continues to rotate, and the material that arrives at the flipping station is upright with its feet facing down, so the flipping nozzle will not have an ineffective action.

[0010] Preferably, the discharge end of the central backing plate points to the middle of the outer peripheral backing plate, and the outer peripheral backing plate is located behind the central backing plate.

[0011] In this scheme, if the material plate guided by the central back plate blocks the upright foot, the upright foot will be exposed in the direction of the air blowing from the flip-up nozzle at the outer back plate when it reaches the outer back plate.

[0012] Preferably, the feeding tray is further provided with a material sorting station, which is located before the discharge station. An outer ring guide plate is provided on the outer periphery of the feeding tray, which gradually approaches the center of the feeding tray along the rotation direction. An inner ring guide plate is provided at the center of the feeding tray, which gradually moves away from the center of the feeding tray along the rotation direction. Both the outer ring guide plate and the inner ring guide plate are arc-shaped.

[0013] In this design, the outer guide plate works in conjunction with the inner guide plate to keep the material away from the center of the feeding tray and the annular baffle, thus preventing the spider arm from interfering with the annular baffle and the center of the feeding tray.

[0014] Preferably, the feeding assembly includes a hopper, a lifting conveyor belt, and a horizontal conveyor belt. The hopper is provided with a storage cavity. The lifting conveyor belt is inclinedly disposed at the bottom of the storage cavity. The horizontal conveyor belt is disposed below the discharge end of the lifting conveyor belt, and the discharge end of the horizontal conveyor belt is disposed above the feeding tray.

[0015] In this scheme, the material in the storage chamber will accumulate at the lower end of the lifting conveyor belt, be transported by the lifting conveyor belt and fall onto the horizontal conveyor belt, and then be transported by the horizontal conveyor belt and fall onto the loading tray.

[0016] Preferably, both the central support plate and the outer peripheral support plate are connected to the mounting rod, the mounting rod is connected to the mounting plate, the mounting plate is connected to the mounting shaft, and the mounting shaft is fixedly installed.

[0017] In this design, the mounting shaft supports the center plate and the outer peripheral plate.

[0018] The beneficial effects of this utility model are as follows: the outer peripheral plate aligns the material around the outer ring of the feeding tray, while the central plate aligns the material around the inner ring of the feeding tray. Air is blown from the flipping nozzles. If the flat plate does not obstruct the uprights, the uprights will be forced to flip the entire material. If the flat plate obstructs the uprights while the material is being conveyed by the central plate, the uprights will be exposed in the direction of the air blowing from the flipping nozzles on the outer peripheral plate when they reach it. Therefore, this utility model has substantial features and advancements compared to existing technologies. Attached Figure Description

[0026] See appendix Figure 1-2 In this embodiment, a spider-hand feeding mechanism for a screening machine includes a rotating feeding disc 1. The feeding disc 1 is equipped with an annular baffle 2 on its outer periphery. The feeding disc 1 has a feeding station, a discharging station, and a flipping station, with the feeding station in front and the discharging station behind. The flipping station is located after the discharging station. The feeding station is equipped with a feeding component 3, and the discharging station is equipped with a discharging component 4. The discharging component 4 includes a discharging conveyor belt 5, a spider hand 6, and a camera. The spider hand 6 connects the feeding disc 1 and the discharging conveyor belt 5. The camera is signal-connected to a controller, and the controller is control-connected to the spider hand 6.

[0027] The flipping station is equipped with a central backing plate 7 and an outer peripheral backing plate 8. The central backing plate 7 is located at the center of the feeding tray 1 and gradually moves away from the center of the feeding tray 1 along the rotation direction. The outer peripheral backing plate 8 is located on the outer periphery of the feeding tray 1 and gradually moves closer to the center of the feeding tray 1 along the rotation direction. Both the outer peripheral backing plate 8 and the central backing plate 7 are equipped with flipping air nozzles 9. The air outlet of the flipping air nozzle 9 is inclined downward and the air blowing direction is consistent with the extension direction of the corresponding backing plate. The discharge end of the central backing plate 7 points to the middle of the outer peripheral backing plate 8. The outer peripheral backing plate 8 is located behind the central backing plate 7. Both the central backing plate 7 and the outer peripheral backing plate 8 are connected to the mounting rod 15. The mounting rod 15 is connected to the mounting plate 13. The mounting plate 13 is connected to the mounting shaft 12, and the mounting shaft 12 is fixedly installed.

[0028] In this embodiment, the feeding tray 1 operates intermittently. The material is conveyed to the feeding tray 1 by the feeding component 3 at the feeding station. The state of the material can be classified into three categories: upright with the feet facing up, upright with the feet facing down and the flat plate tilted (supported by the feet and the flat plate together), and upright with the feet facing down and the flat plate horizontal (supported by the feet). The feeding tray 1 carries the material to the discharge station. The controller identifies the state of the material based on the image captured by the camera, controls the spider arm 6 to pick up the material with the feet facing up and place it on the discharge conveyor belt 5. After the material with the feet facing up is discharged, the feeding tray 1 carries the material to the turning station and continues to rotate. The material to be turned in the inner circle is aligned with the center backing plate 7 and moves along the center backing plate 7. The turning nozzle 9 blows air to turn it over. The material that has not been turned over is aligned with the middle of the outer peripheral backing plate 8 and moves along the outer peripheral backing plate 8. The turning nozzle 9 blows air to turn it over. The two turning processes ensure the turning efficiency. For materials that are stacked together, the turning nozzle 9 is used to blow them apart.

[0029] Among them, Spider Hand 6 is a mature technology; the material supported by the upright is not stable, so when the upright is stressed, the material will flip. After the material is flipped, the upright is facing upward. The air blower 9 will only make the material move horizontally along the surface of the feeding tray 1. As for the blowing force, it is set by the debugging personnel through debugging; the extension direction of the outer peripheral plate 8 and the radial direction of the feeding tray 1 are acute angles, the extension direction of the center plate 7 and the radial direction of the feeding tray 1 are acute angles, the mounting plate 13 where the outer peripheral plate 8 is located is slidably positioned and connected to the mounting shaft 12, which can adjust the size of the radial angle between the outer peripheral plate 8 and the feeding tray 1, as well as the position of the center plate 7 pointing to the outer peripheral plate 8.

[0030] See appendix Figure 2The feeding tray 1 is also provided with a material sorting station, which is located before the discharge station. The feeding tray 1 is provided with an outer ring guide plate 10 on its outer periphery. The outer ring guide plate 10 gradually approaches the center of the feeding tray 1 along the rotation direction. The center of the feeding tray 1 is provided with an inner ring guide plate 11, which gradually moves away from the center of the feeding tray 1 along the rotation direction. Both the outer ring guide plate 10 and the inner ring guide plate 11 are arc-shaped.

[0031] In this embodiment, when the feeding tray 1 carries the material through the material handling station, the outer guide plate 10 and the inner guide plate 11 cause the material to concentrate in the middle, making it easier for the spider hand 6 to pick it up. The arc design makes the direction adjustment smooth and reduces the friction between the material and the corresponding guide plate.

[0032] See appendix Figure 1 The feeding assembly 3 includes a hopper 16, a lifting conveyor belt and a horizontal conveyor belt 14. The hopper 16 is provided with a storage cavity. The lifting conveyor belt is inclinedly arranged at the bottom of the storage cavity. The horizontal conveyor belt 14 is arranged below the discharge end of the lifting conveyor belt. The discharge end of the horizontal conveyor belt 14 is arranged above the feeding plate 1.

[0033] In this embodiment, the hopper 16 is equipped with an openable and closable cover. When the cover is opened, the operator can pour materials into the storage chamber. The lifting conveyor belt gradually lifts the material deposited at the lower end and drops it onto the horizontal conveyor belt 14. The corresponding conveyor belt is driven by a motor, and the discharge end of the lifting conveyor belt is equipped with an inclined downward guide plate.

[0034] The above description represents the preferred embodiment of this utility model. It should be noted that the scope of protection of this utility model is not limited thereto. For those skilled in the art, various improvements, modifications, or equivalent substitutions can be made without departing from the equivalent inventive concept disclosed in this utility model, and these can also be considered as part of the scope of protection of this utility model.
