Description

Technical Field

[0001] The utility model relates to the field of fruit sorting, in particular to a fruit picking and supporting device for multi-stage sorting. Background Art

[0002] Patent application number "202011344249.6," titled "A Circular Weighing and Sorting Device and Method for Fruit," is a patent previously filed by our company. Existing fruit sorting typically involves lifting and loading the fruit, then feeding it into a hopper, where it is then weighed and sorted as the hopper moves forward along a chain. This existing method involves knocking the hopper to one side after weighing it, dumping the fruit into a corresponding collection area. For peaches, pears, apples, and other fruits, turning them over can damage them, making them unsuitable for sorting and packing spherical fruits with delicate skin.

[0003] Therefore, this type of fruit needs to be transported using a protective fruit tray, but the fruit tray needs to be moved to the designated position after weighing to remove the fruit, which requires the design of a suitable dial mechanism. Summary of the Invention

[0004] The technical problem to be solved by the utility model is to provide a multi-stage sorting and fruit-picking device, which can send the fruits to the corresponding packing areas and provide driving force for the fruit sorting.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0006] A multi-stage fruit selection device includes a conveyor line. On one side of the conveyor line, multiple groups of lever swing mechanisms are arranged at intervals along the length direction. On the other side of the conveyor line, multiple groups of first roller conveyor lines are arranged at intervals along the length direction. Each group of first roller conveyor lines corresponds to the position of each lever swing mechanism. A conveyor belt is provided at the output end of each group of first roller conveyor lines.

[0007] There are two groups of lever swing mechanisms at each location, and a partition is fixed in the middle of the upper part of each corresponding first roller conveyor line and conveyor belt along the length direction. The partition divides the first roller conveyor line and conveyor belt into left and right halves.

[0008] The shift lever swing mechanism comprises a shift lever, one end of which is rotatably mounted on the second mounting plate, and the other end of which is driven to rotate by a driving mechanism.

[0009] The driving mechanism is a first cylinder, the cylinder body of the first cylinder is rotatably mounted on the second mounting plate, and the piston rod of the first cylinder is rotatably connected to the shifting rod and drives the shifting rod to rotate.

[0010] The driving mechanism includes a cam, which is mounted on the second mounting plate and driven to rotate by the second motor; a tension spring is also provided on the second mounting plate, and the shifting rod is pulled by the tension spring and keeps in contact with the cam.

[0011] The shifting rod contacts the cam through the roller.

[0012] The utility model provides a multi-stage selection and fruit picking device, which has the following technical effects:

[0013] 1) By setting up a conveyor line and using the lever swing mechanism to push the fruit tray to the corresponding first roller conveyor line, the first roller conveyor line will forward the fruit tray to the conveyor belt, and then the conveyor belt will move the fruit tray to the packing area, where the fruit tray will be packed into boxes. This will enable the fruit to be distributed to different areas for packing.

[0014] 2) When each lever swing mechanism is a single set, the width of the conveyor belt is slightly larger than the outer diameter of the fruit tray. When each lever swing mechanism is a dual set, the width of the conveyor belt is slightly larger than the outer diameters of the two fruit trays. This means that each lever swing mechanism corresponds to a single-row conveying area for fruit trays, and this single-row conveying area is relatively narrow. The lever's rotation to strike the fruit trays does not produce linear motion. Therefore, a first roller conveyor line is installed between the conveyor belt and the conveyor line. This wider first roller conveyor line acts as an intermediate transition. The guide plate and partitions then slowly guide the fruit trays along the conveyor belt, ensuring smooth movement to the designated conveyor belt location. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] like Figure 1-2 As shown, a multi-stage fruit sorting device includes a conveyor line 1, which can be composed of multiple sets of belt conveyors connected end to end. Multiple sets of lever swing mechanisms 2 are spaced apart along the length of the outer side of the conveyor line 1. Each location can have one or two lever swing mechanisms 2. In this embodiment, two sets are provided.

[0022] A plurality of groups of first roller conveyor lines 3 are arranged at intervals along the length direction on the inner side of the conveyor line 1 , and a conveyor belt 4 is correspondingly arranged on the other side of each group of first roller conveyor lines 3 .

[0023] Each lever swing mechanism 2 corresponds to a set of first roller conveyor lines 3 and a set of conveyor belts 4. The control system controls the lever swing mechanism 2 according to the corresponding weighing structure of the previous weighing mechanism 1 to operate, shifting fruits of different weights to the corresponding first roller conveyor lines 3, and then conveying them forward through the corresponding conveyor belts 4.

[0024] When there are two groups of lever swing mechanisms 2 at each location, in order to ensure orderly transportation, a partition 5 is fixed in the middle above the first roller conveyor line 3 and the conveyor belt 4 along the length direction. The partition 5 divides the first roller conveyor line 3 and the conveyor belt 4 into two halves, left and right. The widths of the left and right halves are matched with the width of the fruit trays, so that the fruit trays are transported forward in a single row.

[0025] After the two sets of shifting rod swing mechanisms 2 shift the materials, they are respectively transported forward through the first roller conveyor line 3 and the left and right halves of the conveyor belt 4, thereby improving the working efficiency.

[0026] The lever swing mechanism 2 comprises a lever 2.1, one end of which is rotatably mounted on a second mounting plate 2.2 via a pin, and one side of the lever 2.1 is driven to rotate by a driving mechanism.

[0027] There are two types of drive mechanisms, such as Figure 3 As shown, the first drive mechanism includes a first cylinder 2.3, which is controlled to extend and retract by a corresponding solenoid valve. The cylinder body of the first cylinder 2.3 is rotatably mounted on the second mounting plate 2.2. The piston rod of the first cylinder 2.3 is rotatably connected to the shift lever 2.1 and can drive the shift lever 2.1 to rotate. During the rotation of the shift lever 2.1, the fruit tray 8 carrying fruit on the conveyor line 1 is pushed onto the first roller conveyor line 3.

[0028] like Figure 4As shown, the second drive mechanism includes a cam 2.4, which is driven to rotate by a second motor 2.5. Furthermore, a tension spring 2.6 is connected to the side of the lever 2.1 away from the hinge point. The other end of the tension spring 2.6 is connected to a connecting post on the second mounting plate 2.2. The tension spring 2.6 acts to keep the lever 2.1 in close contact with the cam 2.4. When the cam 2.4 rotates, the lever 2.1 moves outward or retracts accordingly.

[0029] Preferably, when the driving mechanism is cam driven, a roller 2.7 is installed on one side of the shifting rod 2.1, and the roller 2.7 is in contact with the cam 2.4.

[0030] Preferably, a second photoelectric switch 2.8 is further mounted on the second mounting plate 2.2. The second photoelectric switch 2.8 is used to detect whether the fruit tray 8 carrying the fruit is in place.

[0031] like Figure 2 As shown, preferably, the front end of the partition 5 is a pointed tip, and guide plates 6 are provided on the left and right sides of the first roller conveyor line 3. The distance between the two guide plates 6 is larger toward the conveyor line 1 side and smaller toward the conveyor belt 4 side, forming an eight-shaped structure, which plays a guiding role.

[0032] like Figure 2 As shown, preferably, a first photoelectric switch 7 is provided at the input end of the conveyor belt 4. This first photoelectric switch 7 is used to detect the amount of fruit trays 8 entering the conveyor belt 4. If there are too many fruit trays 8 on the conveyor belt 4, they will form a continuous and accumulated state, disrupting the orderly packaging process at the end of the conveyor belt 4. In this case, the first photoelectric switch 7 feeds back the detection result to the control box, which controls the conveyor belt 4 to stop, preventing accumulation at the subsequent packaging process and ensuring coordinated speed throughout the entire production process.

[0033] Preferably, a rubber pad 2.9 is provided on one side of the lever 2.1 for shifting the material, thereby providing a certain buffering effect when shifting the fruit tray.

[0034] like Figure 2 As shown, the present application provides a first lever swing mechanism and a second lever swing mechanism for protecting both mechanisms at the same time; in the actual production process, the first lever swing mechanism or the second lever swing mechanism is uniformly selected on the same production line as the driving device for sorting the fruit tray 8.

[0035] Working Principle and Process: When a fruit tray 8 passes through conveyor line 1, the corresponding second photoelectric switch 2.8 detects it is in place. The drive mechanism then drives the lever 2.1 to push the corresponding fruit tray 8 onto the first roller conveyor line 3. The tray is then transported forward by the conveyor belt 4. If there are too many fruit trays 8 at the input of conveyor belt 4, with trays 8 closely spaced one behind the other, the first photoelectric switch 7 detects this, and the conveyor line 1, lever swing mechanism 2, and conveyor belt 4 stop. They restart when the packaging area at the output of conveyor belt 4 is clear of congestion.
