Abstract
Description
Technical Field
[0001] This application relates to the technical field of automatic identification and packing operations for fruits, and particularly to a suction head for automatically sucking and packing fruits. Background Art
[0002] Fruits play a crucial role in people's diets. They are not only delicious but also rich in various nutrients, bringing multiple benefits to physical health. Fruits contain a large amount of vitamins, dietary fiber, and trace elements such as potassium, magnesium, and calcium. Vitamins are essential for physical health, helping to enhance the immune system, promote bone health, improve eyesight, and enhance brain function. Trace elements contribute to promoting myocardial activity and accelerating the conversion of cholesterol, thereby reducing the probability of arteriosclerosis. Therefore, fruits are an indispensable part of people's diets to meet the body's need for nutrients.
[0003] Currently, after various fruits ripen, most of them are usually sold overseas, and need to be processed such as packed and sealed before transportation. At present, after fruits are picked, they are operated through an automatic packing and boxing device as shown in the attached Figure 1 description. The specific operation process is as follows: The picked fruits are placed on a conveyor belt for transportation. When it is conveyed below the automatic identification device, the position of each fruit is identified through a camera system. Then, after continuing to convey the fruits below the picking device, the position information of each previously identified fruit is transmitted to this picking device (specifically, this picking device has a soft rubber suction head, and the fruits can be sucked under negative pressure by connecting a driving air pipe). The fruits on the conveyor belt are picked up in sequence and placed in a packing box on the side and arranged in sequence, thus realizing the automatic packing operation of fruits, which can greatly improve the operation efficiency and realize packing automation.
[0004] However, different fruits have different individual sizes, such as apples, kiwis, etc. As Figure 4 shown, when sucking large-sized fruits on the left side of the figure, due to the limited suction area of the suction head and the action of the fruit weight, there is a problem of dropping during and after suction. And as shown on the right side, when the fruit is smaller than the size of the suction head port, contact closure cannot be achieved during suction, resulting in insufficient suction and also a problem of dropping. This not only causes economic losses but also requires frequent replacement of the suction head size during continuous packing operations of different fruits in the factory, affecting the operation efficiency. Summary of the Invention
[0005] In view of the above problems, the present application aims to provide a suction head for automatically sucking and packing fruits. The suction head has an adaptive suction structure with multiple structural types adapted to fruits of different sizes, so as to achieve a stable suction effect, solve the problem that the suction head is not adapted to the fruits and is likely to cause dropping, and at the same time solve the problem of affecting the continuous operation efficiency due to frequent replacement of the suction head.
[0006] To achieve the above object, the technical solution adopted in the present application is as follows: A suction head for automatically sucking and packing fruits, the suction head is in the shape of a flared mouth adapted to the surface structure of the fruits, and a driving suction pipe is connected to the top side of the suction head. It is characterized in that: an adaptive suction structure adapted to fruits of different sizes is arranged on the inner wall surface of the suction head.
[0007] Preferably, the adaptive suction structure is a suction port layer arranged on the inner wall surface of the suction head in sequence and adapted to fruits of different sizes.
[0008] Preferably, a sealing structure that is hermetically attached to the surface of the fruit is also arranged at the bottom edge of the suction head and each suction port layer.
[0009] Preferably, the sealing structure is that the bottom edges of the suction head and each suction port layer are all arranged as corrugated structures.
[0010] The beneficial effect of the present application is that: The present application is provided with an adaptive suction structure adapted to fruits of different sizes on the inner wall surface of the suction head. The adaptive suction structure has multiple structural types adapted to fruits of different sizes and is integrally integrated in a single suction head. When sucking fruits of different sizes, the corresponding adaptive suction structure contacts the fruits, so as to achieve a stable suction effect, solve the problem that the suction head is not adapted to the fruits and is likely to cause dropping, and at the same time solve the problem of affecting the continuous operation efficiency due to frequent replacement of the suction head.
[0011] And through the arranged sealing structure, the bottom edges of the suction head and each suction port layer can be adapted to the surface mechanism of the fruit to achieve the sticking effect, so as to achieve the stable suction of the fruit and further avoid dropping during the process of sucking and transferring the fruit.

[0022] In order to enable ordinary technicians in the art to better understand the technical solution of the present application, the technical solution of the present application will be further described below in conjunction with the accompanying drawings and embodiments.
[0023] Refer to Figures 1 to 9 A suction head for automatically sucking and packing fruits as shown. The suction head 1 is in the shape of a flared mouth adapted to the surface structure of the fruit. A driving suction pipe 2 is connected to the top side of the suction head 1. When the suction head 1 comes into contact with the fruit surface, a suction negative pressure is generated in the suction head 1 through the driving suction pipe 2, and under the drive of the picking device, the sucked fruit can be transferred to the packing box beside for placement.
[0024] To solve the problem that the current single suction head 1 cannot suck fruits of different sizes, as Figure 5 shown, an adapted suction structure for fruits of different sizes is provided on the inner wall surface of the suction head 1. The adapted suction structure has various structural types adapted to fruits of different sizes and is integrally integrated in a single suction head 1. When sucking fruits of different sizes, the corresponding adapted suction structure comes into contact with the fruit, so as to achieve a stable suction effect, solve the problem that the suction head 1 is not adapted to the fruit and is likely to cause dropping, and at the same time solve the problem of affecting the continuous operation efficiency due to frequent replacement of the suction head 1.
[0025] Specifically, as Figure 5 shown, the adapted suction structure is suction port layers 11 adapted to different fruit sizes sequentially arranged on the inner wall surface of the suction head 1. The multiple suction port layers 11 are sequentially arranged up and down on the inner wall surface of the suction head 1 and are formed synchronously with the suction head 1. The low port sizes of the suction head 1 and each suction port layer 11 are different to adapt to fruits of different individual sizes. As Figure 6As shown, for fruits of different sizes, the adapted suction port layer 11 contacts them, and under the negative pressure of the driving straw 2, the suction and subsequent transfer operations of the fruits are realized.
[0026] As Figure 7 shown, the surface of the fruit is usually irregular, specifically, the surface is uneven and not a standard spherical structure. Therefore, after the suction head 1 and the bottom port of the suction port layer 11 contact the fruit surface, there may be a problem of incomplete sealing (as shown at point a in Figure 7 ). A sealing structure that is closely attached to the fruit surface is also provided at the bottom of the suction head 1 and each suction port layer 11. This sealing structure enables the bottom of the suction head 1 and each suction port layer 11 to adapt to the fruit surface structure and achieve a close-fitting effect, thereby realizing the stable suction of the fruit and further avoiding the fruit from falling during the suction and transfer process.
[0027] Preferably, as Figure 8 shown, the sealing structure is to set the bottom of the suction head 1 and each suction port layer 11 as a corrugated structure (the enlarged structure is as shown in Figure 9 ). This corrugated structure, such as a corrugated skirt structure, can adapt to the fruit surface structure to achieve a sealing effect after flat contact, and further can realize stable suction and transfer operations for fruits with uneven surfaces.
[0028] The principle of this application is that when the suction head 1 of this application sucks the fruit under negative pressure, the suction head 1 moves downward, making the low port of the adapted suction port layer 11 contact the fruit surface, and achieving close contact with the uneven surface of the fruit through the corrugated structure, and realizing sealing under the negative pressure of the suction head 1. Furthermore, the stable suction and subsequent transfer operations of the fruit can be realized through the suction head 1. And it can realize the suction of fruits with different individual sizes by a single suction head 1, solve the problems of fruit dropping during current suction and the need to frequently replace the suction head, and improve the operation efficiency of the automatic fruit boxing operation.
[0029] The above shows and describes the basic principle, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will have various changes and improvements, and these changes and improvements all fall within the scope of this application claimed.
