Consequent catching and overturning type fruit transition device

Abstract

The invention discloses a consequent catching and overturning type fruit transition device which comprises a detection workbench and a discharge workbench, wherein the detection workbench and the discharge workbench are connected end to end; and the detection workbench adopts a roller to convey fruits, the discharge workbench adopts a fruit support provided with a positioning spring leaf and a friction wheel to convey fruits, and the rotation directions of a detection conveying chain and a discharge conveying chain are opposite. When entering a fruit transition area, the roller and the fruit support convey fruits from the top down along with the conveying chains respectively along chain wheels, the fruits leave the roller under the action of inertia and gravity and fall down along a fruit guide concave under the action of buffering limiting of a brush roller, and the fruit support rotates gradually under the action of the positioning spring leaf of the fruit support and a limiting arc board of the fruit support, faces towards the fruits falling down, takes the chance to catch the fruits, and rotates reversely under the action of friction of an overturning arc-shaped friction strip of the fruit support to return to a stable conveying state. The device takes the chance to catch fruits, is stable in transition, does not cause mechanical collision and injuries to fruits, is accurate in transitional phase position, and can be widely applied to grading transition of apples, oranges and other torispherical fruits.

Description

technical field [0001] The invention belongs to the technical field of agricultural product sorting, and relates to automatic fruit sorting assembly line equipment, especially used for fruit transition between quasi-spherical fruits such as apples and citrus fruits between a detection workbench and a discharge workbench. Background technique [0002] Large-scale fruit automatic sorting line equipment generally sets the fruit quality inspection and grading unloading on different workbenches. Grade automatic unloading. The transition speed and transition phase accuracy of the fruit between the two workbenches are directly related to the sorting speed and sorting accuracy of the entire sorting line, and the transition process is also the most likely to cause fruit mechanical and collision damage in the entire sorting process one of the links. [0003] Existing fruit transition devices are basically divided into three types: interspersed transition between fingers, inertial fo...

The Chinese patent number is 95103294.1, and the name is "A device suitable for sorting and transporting especially fruit items according to predetermined standards". It adopts a transitional fruit transition device interspersed between fingers, and the detection table uses rollers with annular grooves to transport fruits. , the fruit is supported between adjacent rollers, and the unloading table uses a claw-type fruit carrier to convey and unload the fruit. In the fruit transition section, the fruit carrier moves from bottom to top through the gap between adjacent rollers The fingers pass through the groove of the roller and lift the fruit out to realize the transition. The transition between the fingers is smooth and the transition phase is accurate, but the claws and the grooved roller are easy to cause fruit indentation

The Chinese patent number is 200710071472.6, and the name is "Phase Adjustment-Based Precise Fruit Transition System". It adopts the inertial forward throwing transition type fruit transition device, and the detection table uses rollers to transport the fruit. The fruit is supported between adjacent rollers and unloaded. The workbench uses trays to transport and unload fruits, and the detection conveyor chain and the discharge conveyor chain rotate in the same direction. In the fruit transition section, the rollers rotate together with the detection conveyor chain along its sprocket from top to bottom, and the trays are conveyed with the discharge. The chain rotates from bottom to top along its sprocket, and the fruit leaves the roller under the action of inertia and gravity, and falls obliquely downward. After being guided and buffered by the transition roller and the brush roller, it falls into the bottom-to-bottom The transition is realized in the tray that has been rotated upwards. The inertial forward throwing transition device has a simple structure, and the transition phase can also meet the practical requirements after precise adjustment. However, the transition process is reversed, which is easy to cause collision damage to the fruit.

The Chinese patent application number is 201010166992.7, and the name is "non-bruised fruit transition conversion device". A clamping transition type fruit transition device is used, and a special clamping transition device is set above the transition area between the detection workbench and the unloading workbench. The fruit is clamped one by one from the detection table by the clamping mechanism, conveyed and placed on the unloading table. The clamping fruit transition device has a smooth transition and precise transition phase, but the structure is complex and the clamping process is easy to adjust. fruit crush damage
