Description

Technical Field

[0001] This application relates to the technical field of fruit packaging, and particularly to a fruit spacing adjustment device adapted to different box types. Background Art

[0002] Fruits, as an important part of our daily diet, contain rich nutritional components and have many benefits to human health. For example, oranges, lemons, strawberries, grapefruits, etc. are rich in vitamin C, and other fruits are also rich in minerals, dietary fiber, carbohydrates, etc. Consuming fruits in moderation for nutritional intake can maintain nutritional balance.

[0003] Currently, for fruits with relatively large individual sizes such as oranges, apples, and kiwis, they are usually packed in boxes for export after being ripe and picked. In order to improve the efficiency of fruit packing operations, currently, a fruit automatic packing machine as shown in the attached instructions is used. Its main working process is to stack the picked fruits on the right side of the conveyor belt. After being conveyed forward, they are located below the camera recognition system. The position information of each fruit is recognized through the camera system. Then, the fruits continue to be conveyed to the lower part of the picking device at the rear. After that, the driving rubber suction head sucks the fruits according to the position information of the fruits and transfers them to the packaging box on the side. Through this fruit automatic packing machine, the rapid automatic packing operation of fruits can be realized, greatly improving the operation efficiency. Figure 1 As shown, the fruits are stacked on the right side of the conveyor belt, conveyed forward and located below the camera recognition system. The position information of each fruit is recognized through the camera system. Then, the fruits continue to be conveyed to the lower part of the picking device at the rear. After that, the driving rubber suction head sucks the fruits according to the position information of the fruits and transfers them to the packaging box on the side. Through this fruit automatic packing machine, the rapid automatic packing operation of fruits can be realized, greatly improving the operation efficiency.

[0004] Although the automatic packing machine can realize the automatic packing of fruits, since the positions of the fruits are uncertain after being poured onto the conveyor belt and they are in a freely placed state, multiple rubber suction heads cannot be set to suck synchronously, so the packing efficiency of the fruits needs to be improved. Moreover, due to different growth environments, the individual sizes of the same type of fruits are different, resulting in inconsistent box type structures of the packaging boxes. As shown in, the placement spacing of smaller fruits in the packaging box is a box type structure with a distance of d1, while the placement spacing of larger fruits in the packaging box is a box type structure with a distance of d2 (as shown in), so it is difficult to synchronously suck a large number of fruits. Figure 3 As shown, the placement spacing of smaller fruits in the packaging box is a box type structure with a distance of d1, while the placement spacing of larger fruits in the packaging box is a box type structure with a distance of d2 (as shown in), so it is difficult to synchronously suck a large number of fruits. Figure 4 shown), so it is difficult to synchronously suck a large number of fruits. Summary of the Invention

[0005] Aiming at the above problems, this application aims to provide a fruit spacing adjustment device adapted to different box types, which can realize the regular placement of fruits. After synchronously sucking a large number of fruits, the packing operation of a single packaging box can be completed at one time, greatly improving the operation efficiency of fruit packing. At the same time, it can realize the synchronous sucking operation after adjusting according to the individual size of the fruits and the box type.

[0006] To achieve the above object, the technical solution adopted in the present application is as follows: A fruit spacing adjustment device adapted to different box types, including a conveyor belt, characterized in that: on the conveyor belt, fruit separating rollers for receiving each fruit are arranged at horizontal and vertical intervals, and a driving mechanism for driving the horizontally adjacent fruit separating rollers to approach or move away from each other is further arranged on the conveyor belt.

[0007] Preferably, on the conveyor belt, a support rod for slidably passing through the fruit separating rollers is arranged horizontally, and a spacing adjustment spring is sleeved on the support rod between adjacent fruit separating rollers.

[0008] Preferably, the driving mechanism includes spacing adjustment plates symmetrically arranged on both sides of the conveyor belt. Each spacing adjustment plate has a spacing adjustment edge for driving the fruit separating rollers to gradually press and deform the spacing adjustment spring, and a fixed spacing edge for positioning and abutting against the fruit separating rollers.

[0009] Preferably, the side end of the fruit separating roller on the horizontal outer side is set as a spherical structure.

[0010] The beneficial effect of the present application is that by arranging fruit separating rollers for receiving each fruit at horizontal and vertical intervals on the conveyor belt, regular placement of fruits can be achieved. Subsequently, the subsequent picking device can set multiple rubber suction heads according to the determined positions of each fruit for synchronous suction and transfer. After realizing synchronous suction of multiple fruits, the operation of packing a single packing box can be completed at one time, greatly improving the operation efficiency of fruit packing.

[0011] By setting the driving mechanism to drive the fruit separating rollers to approach or move away, the spacing between adjacent fruits can be adjusted, so as to adapt to different box types. At the same time, by sliding the rubber suction heads on the frame and adjusting the spacing between the rubber suction heads in advance, synchronous suction operations can be achieved for the adjusted fruit sizes and box types.

[0022] In order to enable ordinary technicians in the field to better understand the technical solution of this application, the technical solution of this application will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] Refer to the attached Figures 1-9 A fruit distance adjusting device adapted to different box types as shown, including a conveyor belt 1, and its current packing operation is as Figure 1 shown. The picked fruits are stacked on the right side of the conveyor belt, and after being conveyed forward, they are located below the camera recognition system. The position information of each fruit is recognized through the camera system. Then, after the fruits continue to be conveyed to the lower part of the picking device at the rear, the driving rubber suction head sucks and transfers them according to the position information of the fruits and places them in the packaging box beside, realizing the automatic packing operation of single fruits.

[0024] To achieve the synchronous suction operation of multiple fruits, as Figure 5 shown, fruit separating rollers 2 for receiving each fruit are arranged at horizontal and vertical intervals on the conveyor belt 1. After the picked fruits are poured on the conveyor belt 1, a single fruit is received between the longitudinally adjacent fruit separating rollers 2, as Figure 6 shown, so as to realize the regular placement of fruits. Then, the subsequent picking device can set multiple rubber suction heads according to the determined positions of each fruit for synchronous suction transfer (and multiple rubber suction heads can be assembled on the same frame body, and through the horizontal slide rail and the vertical slide rail, after synchronously sucking the fruits on the conveyor belt 1, they are transferred to the packaging box beside through the slide rail mechanism), realizing the synchronous suction of multiple fruits and then realizing the packing operation of a single packaging box at one time, greatly improving the operation efficiency of fruit packing.

[0025] And for the adaptable packing operation according to fruits of different sizes and box types, as Figures 5-6As shown in the figure, a driving mechanism for driving the adjacent fruit separating rollers 2 in the horizontal direction to approach or move away from each other is further provided on the conveyor belt 1. By driving the fruit separating rollers 2 to approach or move away through this driving mechanism, the distance between adjacent fruits can be adjusted, so as to adapt to different box structures. At the same time, the rubber suction heads are slidably arranged on the frame. After the distance between the rubber suction heads is adjusted in advance, the synchronous suction operation for the individual size of the fruits and the adjusted box type can be realized.

[0026] To realize the adjustment of the distance between the adjacent fruit separating rollers 2 in the horizontal direction, as Figure 5 shown, a support rod 11 that slidably penetrates the fruit separating rollers is horizontally arranged on the conveyor belt 1, and a distance adjusting spring 3 is sleeved on the support rod 11 between the adjacent fruit separating rollers 2. During adjustment, through the contact drive of the driving mechanism on the outer fruit separating roller 2, the distance adjusting spring 3 between the adjacent fruit separating rollers 2 is squeezed, and then the distance between the fruits received on the fruit separating rollers 2 can be adjusted. After adjustment, the synchronous suction operation of multiple fruits is carried out through the rubber suction heads with the distance adjusted in advance.

[0027] Specifically, as Figure 5 shown, the driving mechanism includes distance adjusting plates 4 symmetrically arranged on both sides of the conveyor belt 1. Each distance adjusting plate 4 has a distance adjusting edge 4a for driving the fruit separating roller 2 to gradually press the distance adjusting spring 3 to deform, and a fixed distance edge 4b that abuts against the fruit separating roller 2 for positioning. The distance adjustment process is as follows: during the synchronous movement of the conveyor belt 1 and the fruit separating rollers 2, when the outer fruit separating roller 2 contacts the distance adjusting edge 4a of the distance adjusting plate 4, it is driven along the distance adjusting edge 4a (preferably an arc or straight line structure) by the distance adjusting plate 4, and squeezes the distance adjusting spring 3 between the adjacent fruit separating rollers 2 ( Figure 5 the acting direction shown by the arrow in the figure), and when it contacts the fixed distance edge 4b, the distance between the adjacent fruit separating rollers 2 adapts to the distance for placing fruits in the box type, realizing the adjustment of the fruit distance. The longitudinal length of the fixed distance edge 4b is the same as the number of rows of fruits placed in the box type, that is, the synchronous fixed distance operation of four rows / five rows of fruits in the box type as shown in Figures 3-4 is realized in the fixed distance edge 4b. For the box type shown in the figure, when the number of fruits placed in each row is four, the corresponding number of rubber suction heads is assembled in each row, and the unabsorbed fruits flow back from the other side of the conveyor belt 1.

[0028] To facilitate the fixed distance adjustment of the fruit distance (such as four columns or five columns of fruits), distance adjusting plates 4 with different widths can be assembled, or transverse adjusting holes ( Figure 7 shown as 4c in the figure) are opened on the distance adjusting plates 4, and the position of the distance adjusting plates 4 is adjusted and the fruit distance is adjusted by horizontally moving the distance adjusting plates 4.

[0029] As Figure 8As shown, during the process of the planar structure of the end face of the outer fruit separating roller 2 coming into contact with and being extruded and driven by the distance adjusting edge 4a, contact friction easily causes axial deflection and jamming between the fruit separating roller 2 and the support rod. Therefore, to facilitate the smooth displacement of the fruit separating roller 2 on the support rod after being extruded, as Figure 9 shown, the side end of the fruit separating roller 2 on the lateral outside is provided with a spherical structure. This spherical structure enables the fruit separating roller 2 to smoothly contact the distance adjusting edge 4a, driving the fruit separating roller 2 to smoothly slide on the support rod and realizing the smooth adjustment of the fruit spacing.

[0030] The principle of this application is as follows: Support rods 11 through which the fruit separating rollers slide horizontally are arranged on the conveyor belt 1, and a distance adjusting spring 3 is sleeved on the support rods 11 between adjacent fruit separating rollers 2; and distance adjusting plates 4 symmetrically arranged on both sides of the conveyor belt 1 are included. Each distance adjusting plate 4 has a distance adjusting edge 4a for driving the fruit separating roller 2 to gradually press and deform the distance adjusting spring 3, and a fixed distance edge 4b that abuts against the positioning of the fruit separating roller 2.

[0031] The distance adjusting process is as follows: During the synchronous movement of the conveyor belt 1 and the fruit separating roller 2, when the outer fruit separating roller 2 comes into contact with the distance adjusting edge 4a of the distance adjusting plate 4, it is driven by the distance adjusting plate 4 along the distance adjusting edge 4a, extruding the distance adjusting spring 3 between the adjacent fruit separating rollers 2. And when it comes into contact with the fixed distance edge 4b, the distance between the adjacent fruit separating rollers 2 adapts to the spacing of the fruits placed in the box type, realizing the adjustment of the fruit spacing. The longitudinal length of the fixed distance edge 4b is the same as the number of rows of fruits placed in the box type, that is, the synchronous fixed distance operation of four / five rows of fruits in the box type is realized in the fixed distance edge 4b. For the box type shown in the figure, when the number of fruits placed in each row is four, then the corresponding number of rubber suction heads is assembled in each row, and the unabsorbed fruits flow back from the other side of the conveyor belt 1, thus realizing the synchronous suction of a large number of fruits and the suction operation suitable for fruits of different individual sizes.

[0032] 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 also have various changes and improvements, and these changes and improvements all fall within the scope of this application claimed.
