Enveloping-reversion type fruit transfer device and method

Abstract

The invention discloses an enveloping-shifting type fruit transfer device and a method. The enveloping-shifting type fruit transfer device comprises a detection table and a discharge table, which are connected in an end-to-end stacked manner. The detection table is provided with rolls for conveying fruits. The discharge table is provided with fruit carriers for conveying fruits. In the fruit transfer section, discharge conveying chain sprockets and detection conveying chain sprockets are coaxial, the discharge conveying chain sprockets are externally meshed with discharge conveying chains, and fruit carriers envelope outside the rolls. The fruit carriers and the rolls convey fruits with respective chains from bottom to top in an arc form, and the fruit carriers constantly face the fruits between each two adjacent rolls. With increase of the arc conveying angle, position relation between the fruit carriers and the rolls is changed gradually till vertical reversion is complete, the fruits gradually leave the rolls and enter the fruit carriers under inertial and gravitational effects of the fruits so as to be transferred, transferring is stable, transferring phases are accurate, the rolls and the fruit carriers are in no relative motion during transferring, the fruits cannot be mechanically injured, and the enveloping-shifting type fruit transfer device and the method are widely applicable to classified transferring of torispherical fruits such as apples, oranges and the like.

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...

Problems solved by technology

The Chinese patent number is ZL95103294.1, and the name is "A device suitable for sorting and transporting especially fruit items according to predetermined standards". The fruit is conveyed by the roller, and the fruit is supported between the adjacent rollers. The unloading table uses the claw-type fruit bracket to convey and unload the fruit. In the fruit transition section, the fruit bracket automatically passes through the gap between the adjacent rollers. Passing from bottom to top, 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; Chinese Patent No. ZL200710071472.6, titled "Phase Adjustment-Based Precise Fruit Transition System", adopts an inertial forward throw transition type fruit transition device, and the detection table uses rollers to transport fruits, and the fruits are supported on adjacent rollers In between, the unloading table uses trays to convey and unload fruits, and the detection conveyor chain and the unloading conveyor chain rotate in the same direction. In the fruit transition section, the rollers rotate along with the detection conveyor chain along its sprocket from top to bottom. The tray rotates from bottom to top along with the unloading conveyor chain along its sprocket, and the fruit leaves the roller under the action of inertia and gravity, and falls obliquely downward, and is guided and buffered by the transition roller and the brush roller. Falling into the tray that rotates from bottom to top to realize the transition, the inertial forward throwing transition device has a simple structure, and the transition phase can meet the practical requirements after precise adjustment, but the transition process is reversed, which is easy to cause fruit collisions damage; the Chinese patent application number is 201010166992.7, and the name is "non-bruised fruit transition conversion device". The transition device, the clamping mechanism clamps the fruits one by one from the detection table, transports and places them on the unloading table. The clamping fruit transition device has a smooth transition and accurate transition phase, but the structure is complex and the clamping The process is easy to cause extrusion damage to the fruit
